Background
Generally, LNG is known to be a clean fuel, and the reserve is also richer than petroleum, and the amount of LNG used has been drastically increased as mining and transportation technologies develop. Such LNG is usually stored in a liquid state by lowering the temperature of methane as a main component to-162 ℃ or below at 1 atm, and the volume of liquefied methane is about 1:600 of the volume of methane in a gaseous state in a standard state, and the specific gravity is 0.42, which is about 1:2 of the specific gravity of crude oil.
LNG is liquefied and transported due to its ease of transportation, and then vaporized for use. However, there is a concern that LNG vaporization facilities are installed on land due to natural disasters and terrorism risks.
In this way, attention has been paid to equipment for supplying vaporized Natural Gas (Natural Gas) to land by providing a regasification facility in an LNG carrier that carries liquefied Natural Gas (Liquefied Natural Gas) instead of a conventional liquefied Natural Gas regasification system provided on land.
In the LNG regasification plant system, LNG stored in a liquefied gas storage tank is pressurized by a booster pump and supplied to an LNG vaporizer, and the LNG vaporizer is vaporized to NG and then supplied to a land where necessary. Here, a large amount of energy is required in the process of heat exchange for increasing the temperature of LNG in the LNG vaporizer. Therefore, in order to solve the problem of waste caused by inefficient exchange of energy used in the process, various heat exchangers for efficient regasification are being studied.

Detailed Description
The objects, specific advantages and novel features of the present invention will become more apparent from the following detailed description of preferred embodiments and examples when considered in conjunction with the drawings. In the present specification, when reference is made to structural members of each drawing, the same reference is made to the same structural member as much as possible even when the reference is made to different drawings. In the description of the present invention, when it is determined that the detailed description of the related known techniques will obscure the gist of the present invention, detailed description thereof will be omitted.
In the following description, liquefied gas is used as a concept that encompasses all of the gaseous fuels stored in a liquid state, such as LNG, LPG, ethylene, ammonia, etc., and is expressed as liquefied gas for convenience even when the liquefied gas is not in a liquid state due to heating or pressurization. The same applies to the vaporised gas. In addition, for convenience, LNG may be used as a concept including NG in a supercritical state or the like in addition to NG (Natural Gas) in a liquid state, and boil-off gas may be used as a concept including not only boil-off gas in a gaseous state but also liquefied boil-off gas.
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Fig. 1 is a conceptual diagram of a ship having a gas regasification system according to a conventional embodiment.
As shown in fig. 1, a conventional gas regasification system 1 includes a liquefied gas storage tank 10, a feed pump 20, a buffer tank 30, a vaporizer 40, and a need 70.
In the conventional gas regasification system 1, liquefied gas in a liquid state is pumped from the liquefied gas storage tank 10 by the feed pump 20, sent to the booster pump 21 through the buffer tank 30, pressurized by the booster pump 21, then heated by the heat source in the vaporizer 40 to be regasified, and then supplied to the required portion 70.
In the gas regasification system 1, a plurality of liquefied gas storage tanks 10 are arranged in the hull 100, while the recondensor 30, booster pump 21, and vaporizer 40 are arranged in a regasification unit chamber 1000, and the regasification unit chamber 1000 is arranged above the upper deck 104 of the bow member 101.
The arrangement of the plurality of structures such as the recondensor 30, the booster pump 21, and the carburetor 40 is because the liquefied gas is composed of explosive substances, and thus the liquefied gas is not provided in the interior of the closed hull 100 having poor circulation properties, and safety is ensured.
The vaporizer 40 receives the first heat medium by a seawater heat exchanger 41 and a heat source pump 42 provided in the heat source circulation line L3, and re-vaporizes the liquefied gas, and uses an explosive refrigerant such as propane or butane as the first heat medium. Accordingly, the seawater heat exchanger 41 and the heat source pump 42 for supplying heat source to the vaporizer 40 are also disposed above the upper deck 104 and driven, as in the case of the plurality of configurations of the gas regasification system 1.
On the other hand, the seawater pump 51 configured to supply seawater to the seawater heat exchanger 41 is located only in the engine room 51 according to the arrangement conditions inside the hull 100, and thus the length of the seawater line L4 connecting the seawater heat exchanger 41 and the seawater pump 51 becomes considerably long. The seawater line L4 has corrosion resistance as compared with the heat source circulation line L3, and a large amount of seawater is supplied to the seawater heat exchanger 41, so that there is a problem in that the cost is relatively high.
In addition, since the explosive refrigerant is contained as described above, the position of the refrigerant disposed in the hull 100 is limited, and there is a problem that the space utilization in the hull 100 is seriously impaired.
The present invention has been developed to solve such problems, and the following description is made in detail.
The undescribed reference numerals L1, L2, 61, 102, 103, 105, H1, H2, E, S, P, ER, D are respectively the liquefied gas supply line L1, the regasification line L2, the second demand 61, the center portion 102, the stern portion 103, the bottom portion 105, the seawater inflow port H1, the seawater outflow port H2, the engine E, the propeller shaft S, the propeller P, the engine room ER, the deck plate D, and are described in detail in the embodiments of the present invention described in fig. 2 to 4 below.
Fig. 2 is a conceptual diagram of a ship having a gas regasification system of an embodiment of the present invention.
As shown in fig. 2, the gas regasification system 2 of the present embodiment includes a liquefied gas storage tank 10, a feed pump 20, a booster pump 21, a buffer tank 30, a vaporizer 40, a second need 61, a first need 70, and a boil-off gas compressor 80.
For convenience, in the embodiment of the present invention, the liquefied gas storage tank 10, the feed pump 20, the booster pump 21, the buffer tank 30, the vaporizer 40, the second necessity 61, the first necessity 70, and the like are given the same reference numerals as those of the respective structures of the conventional gas regasification system 1, but do not necessarily refer to the same structures.
The ship provided with the gas regasification system 2 has a hull 100, and the hull 100 is configured of a bow part 101, a center part 102, a stern part 103, an upper deck 104, and a stern part 105, and a propeller shaft S transmits power generated by an engine E disposed in a nacelle ER of the stern part 103 to a propeller P to operate, thereby propelling the ship.
In addition, as for the ship, a liquefied gas regasification ship (LNG RV) having the gas regasification system 2 provided in a liquefied gas carrier (not numbered) or a floating liquefied gas storage and regasification Facility (FSRU) may be used so that the liquefied gas can be supplied to an onshore terminal after being regasified at sea.
Next, a gas regasification system 2 according to an embodiment of the present invention will be described with reference to fig. 2.
Before explaining the individual structures of the gas regasification system 2 of the embodiment of the present invention, a plurality of basic flow paths for organically connecting the individual structures are explained. Here, the flow path may be a channel Line (Line) through which the fluid flows, but is not limited thereto, and may be any structure capable of allowing the fluid to flow.
In the embodiment of the present invention, a liquefied gas supply line L1, a regasification line L2, a heat source circulation line L3, a seawater line L4, a vapor line L5, a boil-off gas supply line L6, and a boil-off gas branch line L7 may be further included. A plurality of valves (not shown) capable of adjusting the opening degree may be provided in each line, and the supply amount of the boil-off gas or the liquefied gas may be controlled according to the opening degree adjustment of each valve.
The liquefied gas supply line L1 connects the liquefied gas storage tank 10 and the buffer tank 30, and has a feed pump 20, and the liquefied gas stored in the liquefied gas storage tank 10 can be supplied to the buffer tank 30 by the feed pump 20. In this case, the liquefied gas supply line L1 may be connected to the buffer tank 30 while being branched from the upstream of the buffer tank 30 to be directly connected to the regasification line L2.
The regasification line L2 connects the buffer tank 30 to the first demand 70, and includes the booster pump 21 and the vaporizer 40, and can supply the liquefied gas temporarily stored in the buffer tank 30 or the liquefied gas directly supplied from the liquefied gas supply line L1 to the first demand 70 by pressurizing the liquefied gas by the booster pump 21 and then regasifying the liquefied gas by the vaporizer 40.
The heat source circulation line L3 circulates and connects the vaporizer 40, the seawater heat exchanger 41, and the heat source pump 42, thereby circulating the first heat medium to each structure. Here, the heat source circulation line L3 may have a smaller diameter than the seawater line L4.
The heat source circulation line L3 is configured to have a common line (common line) for each heat source supply line L3 connected to the carburetor 40 (shown in fig. 6 and 7) including 4 skid blocks, the seawater heat exchanger 41, and the heat source pump 42. At this time, in the carburetor 40, first to fourth carburetor skid blocks 401 to 404 (shown in fig. 6 and 7) are provided on the first to fourth cabins 401a to 401d (shown in fig. 6 and 7), and the first to fourth skid blocks 401 to 404 (shown in fig. 6 and 7) can be connected to the respective branched heat source supply lines L3a to L3d (shown in fig. 6 and 7) branched from the heat source supply line L3.
At this time, the heat source supply lines L3, which are common lines, are formed only in two when penetrating the upper deck 104, and have an effect of improving the durability of the upper deck 104 of the bow 101, and reducing the possibility of leakage of the heat source, thereby improving the system reliability. Further, the heat source supply lines L3 may be formed in parallel, whereby the flow rate of glycol water that can be accommodated in one heat source supply line L3 can be sufficiently ensured. In this case, the number of lines penetrating the upper deck 104 of the bow 101 may be 4.
The seawater line L4 has a seawater pump 51 and a seawater heat exchanger 41, and connects the seawater inlet port H1 and the seawater outlet port H2, and can supply seawater to the seawater heat exchanger 41 through the seawater pump 51. Here, the seawater line L4 may have a diameter larger than that of the heat source circulation line L3, and a material having corrosion resistance may be applied to the inside of the seawater line L4.
The steam line L5 connects the second demand 61 to the steam heat exchanger 62, and the steam generated at the second demand 61 may be supplied to the steam heat exchanger 62.
The vapor supply line L6 connects the liquefied gas storage tank 10 and the buffer tank 30, and has a vapor compressor 80, and can supply the vapor generated in the liquefied gas storage tank 10 to the buffer tank 30 after the vapor is pressurized by the vapor compressor 80. At this time, the evaporation gas supply line L6 may be connected to the lower side of the buffer tank 30.
The vapor-gas branch line L7 may branch from the vapor-gas compressor 80 downstream of the vapor-gas supply line L6 to be connected to the second demand 61, and may supply the vapor gas pressurized by the vapor-gas compressor 80 to the second demand 61.
Next, a description will be given of an individual configuration for realizing the gas regasification system 2 by organically forming the lines L1 to L7 described above.
The liquefied gas storage tank 10 stores liquefied gas to be supplied to the first required place 70. The liquefied gas storage tank 10 needs to store the liquefied gas in a liquid state, and in this case, the liquefied gas storage tank 10 may have a pressure tank shape.
Here, the liquefied gas storage tanks 10 are disposed inside the hull 100, and as an example, 4 liquefied gas storage tanks 10 may be formed in front of the engine room. The liquefied gas storage tank 10 may be a membrane tank, for example, but is not limited thereto, and may be a tank of various forms such as a stand-alone tank, and is not particularly limited.
In the liquefied gas storage tank 10, a cofferdam (coupler dam) 106 may be disposed between the liquefied gas storage tanks 10, or the cofferdam 106 may be disposed between the engine room ER and the liquefied gas storage tank 10.
The feed pump 20 is provided on the liquefied gas supply line L1, and may be provided inside or outside the liquefied gas storage tank 10 to supply the liquefied gas stored in the liquefied gas storage tank 10 to the buffer tank 30.
Specifically, the feed pump 20 is provided between the liquefied gas storage tank 10 and the buffer tank 30 on the liquefied gas supply line L1, and can supply the liquefied gas stored in the liquefied gas storage tank 10 to the buffer tank 30 by pressurizing the liquefied gas once.
The feed pump 20 may pressurize the liquefied gas stored in the liquefied gas storage tank 10 to 6bar to 8bar to supply the liquefied gas to the buffer tank 30. Here, the feed pump 20 may pressurize the liquefied gas discharged from the liquefied gas storage tank 10 to slightly raise the pressure and temperature thereof, and the pressurized liquefied gas may remain in a liquid state.
At this time, in the case where the feed pump 20 is provided inside the liquefied gas storage tank 10, the feed pump 20 may be a hidden pump, and in the case where the feed pump 20 is provided outside the liquefied gas storage tank 10, the feed pump 20 may be provided at a position inside the hull H lower than the level of the liquefied gas stored in the liquefied gas storage tank 10, and may be a centrifugal pump.
The booster pump 21 may be provided between the buffer tank 30 and the vaporizer 40 on the liquefied gas supply line L1, and may pressurize the liquefied gas supplied from the feed pump 20 or the liquefied gas supplied from the buffer tank 30 to 50bar to 120bar and then supply the pressurized liquefied gas to the vaporizer 40.
The booster pump 21 may pressurize the liquefied gas according to the pressure required at the first requirement 70, and the booster pump 21 may be a centrifugal pump. Here, the booster pump 21 may be provided on the upper side of the upper deck 104 of the bow portion 101.
The buffer tank 30 may be connected to the liquefied gas supply line L1, and may receive the liquefied gas supplied from the liquefied gas storage tank 10 to temporarily store the liquefied gas.
Specifically, the buffer tank 30 may receive the liquefied gas stored in the liquefied gas storage tank 10 from the feed pump 20 through the liquefied gas supply line L1, temporarily store the supplied liquefied gas, thereby separating the liquefied gas into a liquid phase and a gas phase, and supply the separated liquid phase to the booster pump 21.
That is, the buffer tank 30 temporarily stores the liquefied gas to separate into a liquid phase and a gas phase, and then supplies the complete liquid phase to the booster pump 21 to allow the booster pump 21 to satisfy an effective Cavitation margin (NPSH), whereby Cavitation in the booster pump 21 can be prevented.
The buffer tank 30 may be connected to the boil-off gas supply line L6 to receive the boil-off gas generated in the liquefied gas storage tank 10 and temporarily store the same.
Specifically, the buffer tank 30 may receive the boil-off gas generated from the liquefied gas storage tank 10 from the boil-off gas compressor 80 through the boil-off gas supply line L6 to perform temporary storage.
In this way, the buffer tank 30 can perform recondensing by exchanging heat between the liquefied gas received from the liquefied gas supply line L1 and temporarily stored and the vapor gas received from the vapor gas supply line L6 and temporarily stored. Here, the buffer tank 30 may be formed as a pressure vessel capable of withstanding pressure, and may withstand 6 to 8 bar (bar) or 6 to 15 bar (bar).
Accordingly, the buffer tank 30 receives the boil-off gas and the liquefied gas at a pressure of approximately 6 to 8bar (or alternatively 6 to 15 bar) through the boil-off gas compressor 80 and the feed pump 20, and increases the recondensing efficiency as compared with the low-pressure boil-off gas or liquefied gas, and recondenses the boil-off gas or liquefied gas in a state of maintaining the pressure and supplies the recondensed gas or liquefied gas to the booster pump 21, thereby having an effect of reducing the compression load of the booster pump 21.
At this time, the buffer tank 30 may have a spraying portion 31 and a packing portion 32 to effectively recondense the liquefied gas and the evaporated gas which are temporarily stored.
The spraying portion 31 may be formed to extend from a distal end portion of the liquefied gas supply line L1 into the buffer tank 30, and may be provided above the filler portion 32, and may spray the liquefied gas supplied through the liquefied gas supply line L1 to the filler portion 32.
The spraying portion 31 may spray the liquefied gas in a liquid phase to increase the contact area of the liquefied gas with the evaporation gas, and may perform a similar function as the packing portion 32.
The packing 32 may be provided at the center of the inside of the buffer tank 30, and a member such as crushed stone may be formed inside the packing 32 so as to enlarge the surface area where the liquefied gas supplied to the liquefied gas supply line L1 and the evaporation gas supplied to the evaporation gas supply line L6 contact each other. That is, the packing 32 can form many voids by crushed stone formed in the packing 32, and the liquefied gas can flow through the voids, thereby increasing the contact area with the evaporated gas.
In this way, the packing 32 can increase the heat exchange efficiency between the liquefied gas and the evaporated gas to improve the recondensing rate.
Here, when the packing portion 32 is used as a reference, the buffer tank 30 is connected to the liquefied gas supply line L1 at an upper position and connected to the evaporation gas supply line L6 at a lower position, so that the flow properties of the liquid phase and the gas phase can be utilized to the maximum. In addition, the buffer tank 30 may be disposed on the upper side of the upper deck 104 of the bow 101.
The vaporizer 40 may be provided on the regasification line L2 to regasify the high-pressure liquefied gas discharged from the booster pump 21.
Specifically, the vaporizer 40 may be provided in the regasification line L2 between the first demand point 70 and the booster pump 21, and may vaporize the high-pressure liquefied gas supplied from the booster pump 21 to supply the liquefied gas in a state required for the first demand point 70.
The vaporizer 40 may receive the first heat medium through the heat source circulation line L3, and heat-exchange the first heat medium with the liquefied gas to vaporize the liquefied gas, and circulate the first heat medium heat-exchanged with the liquefied gas through the heat source circulation line L3 again.
In order to continuously supply the heat source to the first heat medium, the vaporizer 40 may have a seawater heat exchanger 41 and a steam heat exchanger 62 on the heat source circulation line L3, and may additionally have a heat source pump 42 to circulate the first heat medium on the heat source circulation line L3.
In this case, as the first heating medium for vaporizing the liquefied gas, ethylene Glycol Water (Glycol Water), sea Water (Sea Water), steam (stem), or a non-explosive heating medium such as engine exhaust gas may be used for the vaporizer 40, and the vaporized liquefied gas having a high pressure may be supplied to the required portion 70 without pressure fluctuation.
Here, the carburetor 40 may be disposed above the upper deck 104 of the bow portion 101, and the seawater heat exchanger 41, the steam heat exchanger 62, and the heat source pump 42 may be modularized and disposed in a space inside the bow portion 101.
As an example, the seawater heat exchanger 41, the steam heat exchanger 62, and the heat source pump 42 may be modularly disposed on the side surface of the interior of the hull 100, and may preferably be disposed in the interior of the engine room ER, but may preferably be disposed in the interior space of the bow portion 101.
Next, an example of the arrangement of the seawater heat exchanger 41, the steam heat exchanger 62, and the heat source pump 42 in the inner space of the bow portion 101 will be described with reference to fig. 5 to 9, and an example of the arrangement in one side or both sides of the engine room ER will be described.
The seawater heat exchanger 41, the steam heat exchanger 62, and the heat source pump 42 are vertically partitioned by at least one deck for vertically partitioning the internal space of the hull 100. As an example, in the embodiment of the present invention, the inner space of the bow 101 is divided up and down by the first deck plate D1 and the second deck plate D2, but is not limited thereto.
The seawater heat exchanger 41 is provided in the seawater line L4 and the heat source circulation line L3, and functions to exchange heat between the seawater received through the seawater line L4 and the first heat medium received through the heat source circulation line L3, thereby transferring the heat source of the seawater to the first heat medium.
The seawater heat exchanger 41 may be provided on the first deck D1 in the inner space of the bow portion 101, and may be disposed adjacent to the seawater outlet port H2.
As shown in fig. 1, in the conventional gas regasification system 1, the seawater heat exchanger 41 and the heat source pump 42 are disposed above the upper deck 104 of the hull 100, and the length of the seawater line L4 connecting the seawater pump 51 and the seawater heat exchanger 41 is very long. The cost of the sea water line L4 is very high because the sea water line L4 should have corrosion resistance and a pipe having a large diameter should be used, and as described above, the conventional sea water line L4 has a problem of a relatively high construction cost because the length thereof is very long.
In this way, in the embodiment of the present invention, the seawater heat exchanger 41 and the heat source pump 42 are modularized to be disposed on the first deck D1 in the inner space of the bow portion 101, particularly, at a position adjacent to the seawater outlet port H2, so that the seawater line L4 can be significantly reduced, thereby having an effect that the construction cost can be minimized.
As described above, in the embodiment of the present invention, the first heat medium is a non-explosive heat medium, so that a plurality of structures (heat source supply devices) using the first heat medium can be arranged inside the hull 100, and the plurality of structures (heat source supply devices) using the first heat medium can be made compact by being modularized, so that the plurality of structures (heat source supply devices) using the first heat medium can be arranged inside the hull 100.
In addition, in the embodiment of the present invention, a seawater pump 51 provided on the seawater line L4 may be further included.
The seawater pump 51 may supply seawater to the seawater heat exchanger 41 through the seawater line L4, and the seawater pump 51 may be disposed on the bottom 105 (preferably, a position adjacent to the seawater inlet port H1) in the inner space of the bow portion 101.
As shown in fig. 1, in the conventional gas regasification system 1, the seawater pump 51 is disposed in the engine room ER, and the length of the seawater line L4 connecting the seawater pump 51 and the seawater heat exchanger 41 is extremely long. Therefore, as described above, the conventional seawater line L4 has a very long length, and thus has a problem of a relatively high construction cost.
As described above, in the embodiment of the present invention, the seawater pump 51 is disposed on the bottom 105 in the inner space of the bow 101, and particularly, the seawater pump 51 is disposed at a position adjacent to the seawater inlet port H1, so that the seawater line L4 can be significantly reduced, thereby having an effect that the construction cost can be minimized.
The steam heat exchanger 62 is provided in the steam line L5 and the heat source circulation line L3, and performs a function of additionally transferring the heat source of the seawater to the first heat medium by exchanging heat between the steam received through the steam line L5 and the first heat medium received through the heat source circulation line L3. Here, the steam may exchange heat with the first heat medium after utilizing the seawater. That is, in the case where the heat source supplied from the seawater is insufficient, the steam may be supplied as a second auxiliary means to the first heat medium in order to supplement the heat source.
The steam heat exchanger 62 may be provided on the first deck D1 in the inner space of the bow portion 101.
The heat source pump 42 may be disposed on the heat source circulation line L3 to circulate the first heat medium in the seawater heat exchanger 41 and the steam heat exchanger 62 disposed on the heat source circulation line L3.
The heat source pump 42 may be modularized with the seawater heat exchanger 41 and provided in the inner space of the bow portion 101, and the heat source pump 42 is disposed on the second deck plate D2 in the inner space of the bow portion 101, and the heat source pump 42 is disposed so as to be vertically partitioned from the seawater heat exchanger 41 through the first deck plate D1.
As described above, in the embodiment of the present invention, the non-explosive heat medium is used as the first heat medium, and a plurality of structures (heat source supply devices) using the first heat medium can be modularized to be disposed inside the hull 100. In the embodiment of the present invention, a plurality of structures (heat source supply devices) using the first heat medium are arranged inside the hull 100, and a system configuration and a plurality of lines are provided as shown in fig. 4 in order to reduce the circulation flow rate of the first heat medium.
Next, the configuration and structure of the gas regasification system will be described in detail with reference to fig. 4.
Fig. 4 is a conceptual diagram illustrating a gas regasification system of an embodiment of the present invention.
Here, the vaporizer 40 may be constituted by the first heat exchanger 401 and the second heat exchanger 402 in the regasification line L2, the seawater heat exchanger 41 may be constituted by the first seawater heat exchanger 411 and the second seawater heat exchanger 412 in the heat source circulation line L3, and the steam heat exchanger 62 may be constituted by the first heater 621 and the second heater 622 in the heat source circulation line L3.
In this case, the first heat exchanger 401 may function to raise the temperature of the vaporized liquefied gas by a trim heater, and the second heat exchanger 402 may function to vaporize the liquefied gas in the liquid phase to the liquefied gas in the gas phase by an LNG Vaporizer (LNG Vaporizer). In addition, the first heater 621 and the second heater 622 may be electric heaters.
In addition, in the embodiment of the present invention, the seawater parallel line L4a and the steam parallel line L5a may be further included, the seawater parallel line L4a may be branched from the seawater line L4 to be connected in parallel with the second seawater heat exchanger 412, and the steam parallel line L5a may be branched from the steam line L5 to be connected in parallel with the second heater 622.
Referring to fig. 4, to analyze the structure of the vaporizer 40 of the gas regasification system 2 of the present embodiment in detail, a first heat exchanger 401, a first seawater heat exchanger 411, a second heat exchanger 402, and a second seawater heat exchanger 412 may be sequentially disposed on the heating source circulation line L3. Here, the first heater 621 is provided between the first seawater heat exchanger 411 and the second heat exchanger 402 on the heat source circulation line L3, and the second heater 622 is provided between the second seawater heat exchanger 412 and the first heat exchanger 401 on the heat source circulation line L3. Here, the first heat source may be heated by seawater before the steam is used.
In the embodiment of the present invention, by arranging the above-described plurality of structures in order, the flow rate of the first heat medium can be significantly reduced while maintaining the vaporization rate of the liquefied gas, and thus there is an effect that the plurality of structures (heat source supply means) using the first heat medium can be actually arranged inside the hull 100.
In addition, the gas regasification system 2 of an embodiment of the present invention may further include a pressure maintenance device 94.
The pressure maintaining device 94 maintains the pressure of the first heat medium flowing through the heat source circulation line L3, and is realized by using an inert gas.
In this way, in the embodiment of the present invention, the pressure maintaining device 94 maintains the pressure of the first heat medium using the inert gas, and thus has an effect of being able to be compactly disposed in the inner space of the hull 100.
The second need 61 receives the boil-off gas generated from the liquefied gas storage tank 10 for use as fuel. That is, the second demand portion 61 requires the evaporation gas, and the evaporation gas is driven as a raw material. The second requirement 61 may be a generator (e.g., DFDG), a Gas Combustion Unit (GCU), a boiler (e.g., steam generating boiler), but is not limited thereto.
Specifically, the second demand 61 is connected to the boil-off gas branch line L7 to receive the boil-off gas, the boil-off gas branch line L7 branching downstream from the boil-off gas compressor 80 on the supply boil-off gas supply line L6, and the second demand 61 can receive the boil-off gas pressurized to a low pressure of approximately 1bar to 6bar (15 bar maximum) by the boil-off gas compressor 80 to be used as fuel.
The second demand 61 may be a heterogeneous fuel engine that can use heterogeneous fuel, and not only the evaporated gas but also oil can be used as fuel, but the evaporated gas and the oil are not mixed and supplied, and the evaporated gas or the oil can be selectively supplied. This is to prevent the efficiency of the second demand portion 61 from being lowered by blocking the mixed supply of two substances having different combustion temperatures.
Here, the second demand 61 may be provided on the deck D of the engine room ER provided inside the stern 103, and the second demand 61 may be connected to the above-described steam heat exchanger 62 through the steam line L5.
At this time, the steam line L5 may connect the second required portion 61 located at the stern portion 103 to the steam heat exchanger 62 located at the bow portion 101 through a space provided inside the Hull (Hull) in the form of a double-partition wall of the stern portion 105.
The first need 70 may receive the liquefied gas vaporized by the vaporizer 40 for consumption. Here, the first demand point 70 may receive the liquefied gas in the gas phase obtained by vaporizing the liquefied gas, and may be an onshore terminal installed on land or an offshore terminal installed floating on the sea.
The boil-off gas compressor 80 may pressurize the boil-off gas generated from the liquefied gas storage tank 10 to supply the boil-off gas to the buffer tank 30 or the second required portion 61. Here, the boil-off gas compressor 80 may be disposed in the compressor compartment 81, and the motor compartment 82 may be disposed on a side portion of the compressor compartment 81.
Specifically, the boil-off gas compressor 80 may be disposed on the boil-off gas supply line L6 and pressurize the boil-off gas generated from the liquefied gas storage tank 10 to approximately 6bar to 8bar or 6bar to 15bar to be supplied to the buffer tank 30 or to the second demand 61. At this time, the second demand portion 61 may receive the boil-off gas through the boil-off gas branch line L7 branched from the boil-off gas supply line L6.
A plurality of vapor compressors 80 may be provided to pressurize the vapor in multiple stages, and as an example, 3 vapor compressors 80 may be provided to pressurize the vapor in 3 stages. Here, the 3-stage compressor is merely an example, and is not limited to 3 stages.
In an embodiment of the present invention, an boil-off gas cooler (not shown) may be provided at each rear end of the boil-off gas compressor 80. When the vapor gas is pressurized by the vapor gas compressor 80, the temperature may also rise as the pressure rises, and therefore, in the present embodiment, the temperature of the vapor gas may be reduced again using the vapor gas cooler. The number of the boil-off gas coolers may be the same as the number of the boil-off gas compressors 80, and each of the boil-off gas coolers may be disposed downstream of each of the boil-off gas compressors 80.
In addition, in the embodiment of the present invention, the evaporation gas compressors 80 are arranged in parallel, so that the evaporation gas generated in the liquefied gas storage tank 10 can be accommodated in the case where the amount of the evaporation gas generated in the liquefied gas storage tank 10 increases sharply, or even in the case where one of the evaporation gas compressors 80 is erroneously operated or stopped (shutdown), the other evaporation gas compressor 80 can be operated, so that the evaporation gas generated in the liquefied gas storage tank 10 can be accommodated and processed effectively. Here, the boil-off gas compressor 80 may be disposed at an upper side of the upper deck 104 of the bow part 101.
Thus, the ship with the gas regasification system of the present invention has an effect of maximizing the regasification efficiency of the liquefied gas.
Fig. 3 is a conceptual diagram illustrating a gas regasification system of other embodiments of the present invention.
As shown in fig. 3, the gas regasification system 3 of other embodiments of the present invention includes a liquefied gas storage tank 10, a feed pump 20, a booster pump 21, a buffer tank 30, a vaporizer 40, a second need 61, a first need 70, an boil-off gas compressor 80, a boil-off gas suction unit 90, first and second pressurizing means 91 and 92, and a nitrogen separator 93.
Next, a gas regasification system 3 according to an embodiment of the present invention will be described with reference to fig. 3.
The liquefied gas storage tank 10, the feed pump 20, the booster pump 21, the buffer tank 30, the vaporizer 40, the first heat exchanger 41, the second heat exchanger 42, the second required portion 61, the first required portion 70, and the boil-off gas compressor 80 are identical or similar to the structures described in the gas regasification system 2 of the embodiment of the present invention.
In the embodiment of the present invention, a separation line L8 and a vapor suction line L9 may be further included. A plurality of valves (not shown) capable of adjusting the opening degree may be provided in each line, and the supply amount of the boil-off gas or the liquefied gas may be controlled according to the opening degree adjustment of each valve.
The dividing line L8 may branch downstream of the vaporizer 40 on the regasification line L2, preferably downstream of the first heat exchanger 401, and bypass the boil-off gas intake unit 90 before being connected upstream of the first demand 70.
The split line L8 may directly supply the liquefied gas re-vaporized by the vaporizer 40 to the first needs place 70 without driving the vaporizing gas suction unit 90.
The vapor gas suction line L9 connects the vapor gas suction unit 90 to the liquefied gas storage tank 10, and can supply the vapor gas generated in the liquefied gas storage tank 10 to the vapor gas suction unit 90.
The boil-off gas suction unit 90 may be disposed downstream of the vaporizer 40 on the regasification line L2 to suck the boil-off gas generated from the liquefied gas storage tank 10.
Specifically, the boil-off gas suction unit 90 may be disposed downstream of the vaporizer 40 on the regasification line L2, connected to the liquefied gas storage tank 10 through the boil-off gas suction line L9, and the boil-off gas suction unit 90 may suck the boil-off gas generated in the liquefied gas storage tank 10 through the boil-off gas suction line L9 as a Driving Fluid (Driving Fluid) supplied from the vaporizer 40 through the regasification line L2, then mix and supply the mixed gas to the first demand 70 again through the regasification line L2.
At this time, the boil-off gas suction unit 90 may receive the boil-off gas having a pressure of 50bar to 120bar, suck the boil-off gas of the liquefied gas storage tank 10 having a pressure of 1bar to 1.1bar to mix, and the boil-off gas suction unit 90 may be an air pump (injector), an Ejector (injector), or a jet pump (jet pump).
The vaporized liquefied gas flowing into the boil-off gas suction unit 90 may have a pressure of 50bar to 120bar (preferably 100 bar), and the boil-off gas generated from the liquefied gas storage tank 10 has a pressure of 1.00bar to 1.10bar (preferably approximately 1.06 bar).
The evaporation gas suction unit 90 receives the liquefied gas re-vaporized from the vaporizer 40 as a driving fluid, and sucks the evaporation gas generated from the liquefied gas storage tank 10 to mix, at this time, kinetic energy originally possessed by the driving fluid is converted into kinetic energy of the whole mixed fluid, and then, at an end portion where a cross section of a nozzle (not designated by a reference numeral) of the evaporation gas suction unit 90 is enlarged, the kinetic energy of the mixed fluid is converted into pressure again as the speed of the mixed fluid is reduced.
Thus, the boil-off gas generated from the liquefied gas storage tank 10 can be obtained: a mixed fluid of a pressure lower than a pressure of 50bar to 120bar as an inflow pressure of the driving fluid. As described above, since the first necessary portion 70 cannot be consumed by the pressure, it is necessary to additionally pressurize by an additional pressurizing means, which is a second pressurizing means 92 described later, and then supply the pressurized gas to the first necessary portion 70.
Here, since the pressure of the driving fluid is high, even with a small amount of fluid, the pressure of the intake fluid can be easily increased.
In this way, the gas regasification system 3 of the embodiment of the present invention processes the boil-off gas generated from the liquefied gas storage tank 10 through the boil-off gas suction device 90, and thus it is unnecessary to construct an additional recondensor for recondensing the boil-off gas, thereby having the effect of reducing construction costs, making the system compact, and improving reliability.
The first pressurizing means 91 may be provided between the boil-off gas suction unit 90 and the vaporizer 40 in the regasification line L2, and pressurize the liquefied gas discharged from the vaporizer 40. In this case, the first pressurizing means 91 is a means for pressurizing the gas, and may be a compressor, for example.
Specifically, the first pressurizing means 91 may be disposed between the evaporated gas suction means 90 on the re-evaporation line L2 and the branching point of the branching line L8, and may pressurize the liquefied gas evaporated from the evaporator 40 to 120bar or more, and supply the liquefied gas to the evaporated gas suction means 90.
That is, the first pressurizing means 91 can compensate for the pressure lost in the vaporizer 40 to supply the vaporized gas to the vaporized gas suction unit 90, and can further increase the pressure of the vaporized liquefied gas according to the suction amount of the vaporized gas generated in the liquefied gas storage tank 10, thereby having an effect that the process of the vaporized gas can be effectively performed.
The second pressurizing means 92 may be provided between the boil-off gas suction unit 90 and the first required portion 70 on the regasification line L2, and pressurize the mixed fluid (mixture of the boil-off gas and the boil-off gas) discharged from the boil-off gas suction unit 90. In this case, the second pressurizing means 92 is a means for pressurizing the gas, and may be a compressor, for example.
Specifically, the second pressurizing means 92 may be provided between the connection point of the nitrogen separator 93 and the split line L8 on the regasification line L2, and pressurize the mixed fluid discharged from the vapor gas suction unit 90 to 50bar to 120bar to supply the mixed fluid to the first demand 70.
That is, the second pressurizing means 92 compensates for the pressure lost in the vapor gas suction unit 90 and supplies the pressure to the first required portion 70, and thus has an effect of being able to appropriately adjust the pressure required for the first required portion 70.
The nitrogen separator 93 may be provided between the boil-off gas suction unit 90 and the second pressurizing means 92 on the regasification line L2, and separates and removes nitrogen components in the mixed fluid (mixture of the boil-off liquefied gas and the boil-off gas) discharged from the boil-off gas suction unit 90.
The separated nitrogen may be supplied to a nitrogen demand (not shown) consuming nitrogen in the hull 100, and may be supplied to the pressure maintaining device 94 for maintaining the pressure of the first heat medium, for example.
In the embodiments of fig. 2 to 4 described above, a Cargo distributor room 1001 (Cargo SWBD room) may be arranged on the lower side of the regasification unit room 1000, a ventilation mast V may be arranged on the upper deck 104, and a ship room C and a chimney Ch may be arranged on the upper deck 104 of the engine room ER.
Fig. 5 is a conceptual diagram of a ship having a gas regasification system according to still another embodiment of the present invention, fig. 6 is a conceptual diagram illustrating the gas regasification system according to still another embodiment of the present invention, fig. 7 is a conceptual diagram illustrating the gas regasification system according to still another embodiment of the present invention in detail, and fig. 8 is a conceptual diagram illustrating an ethylene glycol water circulation device according to an embodiment of the present invention.
As shown in fig. 5 to 8, the gas regasification system 4 of other embodiments of the present invention includes a liquefied gas storage tank 10, a feed pump 20, a booster pump 21, a buffer tank 30, a vaporizer 40, a second need 61, a first need 70, and a boil-off gas compressor 80.
In the embodiments of fig. 2 to 4 described above, the following techniques are described: the seawater heat exchanger 41, the steam heat exchanger 62, and the heat source pump 42 are modularized and arranged below the upper deck 104 of the bow part 101, that is, in the inner space of the bow part 101, on the inner side surface of the hull 100. Next, with reference to fig. 5 to 8, an invention in which the seawater heat exchanger 41, the steam heat exchanger 62, and the heat source pump 42 are disposed inside the engine room ER will be described.
The structure not mentioned in the structures shown in fig. 5 to 8 is identical to the vessel comprising the gas regasification system 2, 3 illustrated in fig. 2 to 4. The embodiment illustrated in fig. 5 to 8 differs from the ship comprising the gas regasification system 2, 3 illustrated in fig. 2 to 4, among other things, in the following two points.
First, in the configuration of the regasification unit chamber 1000 for accommodating the booster pump 21, the recondensor 30, and the carburetor 40, in the vessel including the gas regasification systems 2 and 3 described in fig. 2 to 4, the configuration of the gas regasification system 4 shown in fig. 5 to 8 is arranged at the center of the hull, and this point is the first difference point (difference in the arrangement positions of the gas regasification systems) in the configuration of the regasification unit chamber 2000 for accommodating the booster pump 21, the recondensor 30, and the carburetor 40, although the gas regasification systems 104 are arranged on the upper deck 104 of the bow portion 101. In the vessel including the gas regasification systems 2 and 3 described in fig. 2 to 4, the structure of the intermediate heat medium supply device such as the seawater heat exchanger 41, the steam heat exchanger 62, and the heat source pump 42 is disposed below the upper deck 104 of the bow portion 101, that is, inside the bow portion 101, but in the vessel including the gas regasification system 4 shown in fig. 5 to 8, the intermediate heat medium supply device is disposed inside the stern portion 103 (preferably inside the engine room ER), and this difference point is the second difference point (difference in the disposition positions of the intermediate heat medium supply devices).
The following describes in detail the differences described above with reference to fig. 5 to 8.
The liquefied gas storage tank 10, feed pump 20, booster pump 21, surge tank 30, vaporizer 40, first heat exchanger 41, second heat exchanger 42, first need 70, and boil-off gas compressor 80 are the same as or similar to those described in the embodiments of the present invention and the other embodiments of the gas regasification systems 2, 3.
In an embodiment of the present invention, a glycol water storage tank 43, an expansion tank (expansion tank) 44, a regasification unit chamber 2000, a Cargo distribution board chamber 2001 (Cargo SWBD room), a transfer chamber TR (transfer room), a conversion chamber CVT (convert room) may also be included.
Here, the transfer chamber TR and the transfer chamber CVT may be arranged on the third deck D4 (3 rd deck), the Cargo distribution board chamber 2001 (Cargo SWBD room) may be arranged inside the ship chamber C, which may be lower in height than the ship chamber arranged in the ship comprising the gas regasification system 2, 3 of the embodiment of fig. 2 to 4.
In the embodiment of the present invention, a boiler (not shown) previously installed in the engine room ER may be removed, and an intermediate heat medium supply device such as the seawater heat exchanger 41, the heat source pump 42, the glycol water storage tank 43, etc. may be disposed in front of the engine E in the engine room ER.
With the boiler removed, a space for the engine E to move in the stern direction on the fourth deck plate D5 (4 th deck) is ensured, and thereby, it is possible to ensure that in front of the engine E: space for disposing intermediate heat medium supply devices such as a seawater heat exchanger 41, a heat source pump 42, and a glycol water storage tank 43. As described above, the use of the non-explosive heat medium allows the intermediate heat medium supply device to be disposed in the ship and also to be disposed in the engine room ER, so that more space on the upper deck 104 can be ensured, and thus the space utilization of the ship can be increased.
In this case, the engine E may be connected by a motor (not shown), instead of directly connected to the propeller shaft S by DFDE.
Here, the seawater heat exchanger 41 may be provided in 4 stages and disposed on the fourth deck D5 (4 th ck), and the seawater pump 51 may be disposed on the plate D6 (floor). In this way, the difference in height between the seawater pump 51 and the seawater heat exchanger 41 is reduced, and thus the water head of the seawater pump 51 is reduced, thereby having the effect of reducing the OPEX.
In the case of the fourth deck D5 (4 th ck) disposed in the engine room ER, the seawater heat exchanger 41 may be disposed on the seawater surface or lower than the seawater surface. This shortens the discharge line of the seawater discharged from the seawater heat exchanger 41, and prevents a vacuum phenomenon from occurring when the seawater is discharged to the outside.
In the embodiment of the present invention, the glycol water storage tank 43 is a tank for temporarily storing glycol water for repairing the intermediate heat medium supply device (preferably, the seawater heat exchanger 41), and may be disposed on the plate D6 (floor).
That is, as the glycol water storage tank 43 is disposed below the seawater heat exchanger 41, it is not necessary to construct an additional transfer pump for discharging glycol water when repairing the intermediate heat medium supply device, and thus there is an effect of reducing construction costs.
In the embodiment of the present invention, the heat source circulation line L3 may be connected to the carburetor 40 through the upper deck 104 via a cofferdam 106 formed in front of the engine room ER.
Specifically, the heat source circulation line L3 penetrates the cofferdam 106 horizontally from the engine room ER toward the cofferdam 106, enters the cofferdam 106, rises vertically in the cofferdam 106, and then penetrates the upper deck 104 on the cofferdam 106 to be connected to the vaporizer 40 in the regasification unit chamber 2000. At this time, a collecting device (not shown) for collecting the leaked glycol water may be disposed at the lowermost side of the bank 106.
In this way, when the heat source circulation line L3 penetrates the upper deck 104, it is unnecessary to construct an additional ventilation system, and there is an effect of reducing construction costs.
In the embodiment of the present invention, as shown in fig. 6 and 7, each heat source supply line L3 connected to the vaporizer 40, the seawater heat exchanger 41, and the heat source pump 42, which are composed of 4 skid blocks (skids), may be configured as one common line. At this time, the carburetor 40 may be provided with first to fourth carburetor skid blocks 401 to 404 in the first to fourth cabins 401a to 401d, and the heat source supply lines L3a to L3d branched from the heat source supply line L3 may be connected to the first to fourth skid blocks 401 to 404.
That is, conventionally, when the heat source supply lines L3 are connected to the carburettors 40 each constituted by 4 skid blocks, the penetration of the upper deck 104 is 8 (the lead-in line and the lead-out line), and the durability of the upper deck 104 is reduced, but in the embodiment of the present invention, the heat source supply lines L3 configured as the common line are formed only two when penetrating the upper deck 104, and thus have the effect of improving the durability of the upper deck 104, and the possibility of the heat source leaking is reduced, and thus have the effect of improving the system reliability.
In this case, the additional lines may be formed in parallel in the heat source supply line L3, and thus the flow rate of the glycol water that can be accommodated in one heat source supply line L3 can be sufficiently ensured. In this case, the number of lines penetrating the upper deck 104 may be 4.
In the embodiment of the present invention, as shown in fig. 8, the intermediate heat medium supply device is arranged in the order of the expansion tank 44, the seawater heat exchanger 41, the heat source pump 42, and the carburetor 40. Conventionally, the expansion tank 44, the heat source pump 42, the seawater heat exchanger 41, and the carburetor 40 are arranged in this order, but the intermediate heat medium supply device is arranged as shown in fig. 8, so that the allowable pressure of the seawater heat exchanger 41 is reduced, and the construction cost of the seawater heat exchanger 41 is reduced.
Here, the seawater heat exchanger 41 may be a PCHE type heat exchanger, the pressure of the glycol water flowing into the seawater heat exchanger 41 may be approximately 2.5bar, the pressure of the glycol water flowing from the seawater heat exchanger 41 into the heat source pump 42 may be approximately 0.5bar, and the pressure of the glycol water discharged from the heat source pump 42 may be approximately 15bar. At this time, the pressure of the seawater flowing into the seawater heat exchanger 41 may be approximately 2bar to 3bar.
Fig. 9 is a conceptual diagram of the seawater supply device of the present invention.
As shown in fig. 9, the seawater supply device includes seawater tanks SC1 to SC3 for flowing seawater therein, and a seawater pump 51. The seawater supply device of fig. 9 is applicable not only to a ship having the gas regasification systems 2, 3 of fig. 2 to 4, but also to a ship having the gas regasification system 4 of fig. 5 to 8.
In the conventional seawater supply device, a seawater tank (Sea Chest) for flowing seawater is disposed only on the lowest side of the hull, and there is a concern that high-temperature seawater may flow due to the temperature of the seawater discharged from the gas regasification system.
In order to solve the above problems, in the seawater supply device of the present embodiment, seawater tanks SC1 to SC3 are disposed on both side surfaces of the lowermost side of the hull, and when seawater is introduced into first seawater tank SC1 (SeaChest 1) and second seawater tank SC2 (SeaChest 2), the discharge of seawater from the left side surface of the hull is controlled (left discharge in the drawing), and when seawater is introduced into third seawater tank SC3 (SeaChest 3), the discharge of seawater from the right side surface of the hull is controlled (right discharge in the drawing), so that the temperature of seawater introduced into seawater tanks SC1 to SC3 is ensured to be constant.
In addition, in the embodiment of the present invention, the seawater tanks SC1, SC2 on the right side may be divided into two of the first seawater tank SC1 (SeaChest 1) and the second seawater tank SC2 (SeaChest 2). In this case, there is an effect that the temperature of the seawater flowing into the seawater tank can be further ensured to be constant.
The present invention has been described in detail by way of specific examples, but this is only for the purpose of specifically explaining the present invention, and the present invention is not limited thereto, and variations and modifications may be made by those skilled in the art within the technical spirit of the present invention.
The invention is merely modified or changed in the field of the invention, and the specific protection scope of the invention is defined by the claims.
