Definitions
- the invention relates to a method for indirect heat exchange of several Gas flows with a heat / coolant in heat exchanger blocks, in which the Gas flows are passed through a variety of heat exchange passages only one of the gas streams is passed through at least one heat exchanger block. Furthermore, the invention relates to a heat exchange device for indirect Heat exchange of at least two gas flows with a heat / coolant in Heat exchanger blocks, which have a variety of heat exchange passages have.
- the main heat exchanger is usually designed as a plate heat exchanger which has a large number of heat exchange passages for the streams to be treated. In air separation plants in which large amounts of air are processed, several such heat exchanger blocks are necessary to process the air and product quantities.
- the main heat exchanger is usually divided into two blocks from about 20,000 to 30,000 Nm 3 / h of air.
- collectors / distributors necessary to the gas flows from the respective inlet nozzle on the to distribute assigned heat exchange passages or from the Heat exchange passages emerging gas flows into the corresponding Merge outlet connection.
- the collectors / distributors have so far been integrated into the heat exchanger block Distribution zones realized. In these distribution zones there are at least some of the slats that delimit the individual heat exchange passages from one another, arranged obliquely, so that the gas flowing in through the inlet connection into the Heat exchange passages is performed or that from the Heat exchange passages exiting gas flow to the outlet port is redirected.
- the object of the present invention is to provide a method and an apparatus for to develop indirect heating or cooling of multiple gas flows which the pressure loss in the heat exchanger is as low as possible.
- the heat exchange device for indirect heat exchange of at least two gas streams with a heat / coolant in Heat exchanger blocks, which have a variety of heat exchange passages own, is characterized in that the heat exchange passages one Heat exchanger blocks intended for one of the gas flows on two opposite end faces of the heat exchanger block and end with are in flow communication with a collector / distributor, the Collector / distributor over the entire end face of the heat exchanger block extend.
- At least one gas flow is as low as possible Should experience pressure loss, passed through a heat exchanger block through which otherwise no further of the gas flows are carried. Stream of course through this heat exchanger block one or more heat or cold carriers with where the gas flow exchanges its heat.
- Heat exchange passages of this heat exchanger block extend from one Face of the block to the opposite face and run essentially parallel. On the two end faces where the heat exchange passages end a collector / distributor attached to the outside of the heat exchanger block, which the covers the entire end face and a connecting piece for the supply and discharge having.
- the heat exchange passages thus go in without a cross-sectional taper the supply and discharge via and the flow deflection in the collector / distributor takes place slowly.
- the pressure loss in the heat exchanger block and the associated one This minimizes collectors / distributors.
- the invention is particularly suitable in processes in which gas streams, one Have pressure of less than 3.5 bar, preferably between 1.1 and 1.8 bar, in hereinafter referred to as low pressure flows, in indirect heat exchange with a Heat or cold carriers are to be brought. According to the invention, this is done by one heat exchanger block only one of these low-pressure gas flows, i.e. for each of the gas streams that have a pressure of less than 3.5 bar its own heat exchanger block used.
- the method according to the invention is preferably used in low-temperature decomposition of application air application.
- the product of a low pressure column Gas streams withdrawn from the double column rectifier have only a small amount Overpressure of about 0.1 to 0.8 bar above atmospheric pressure, so that a reduction the pressure drop is of great importance. This applies analogously to gaseous Argon product, since the crude argon column also operated under relatively low pressure becomes.
- the gas flows with the feed air in indirect are particularly preferred Heat exchange brought.
- the feed air can be divided into several flows through the heat exchanger blocks at different pressure levels be performed.
- the air supply can be below Pressure column pressure passed through the heat exchanger block and then into the Pressure column can be fed, on the other hand, the feed air can before Heat exchanger block recompressed and after cooling for cooling be relaxed while working.
- the gas stream is passed through the heat exchanger blocks so that it suffers a pressure drop of 120 to 300 mbar, preferably 120 to 200 mbar.
- a pressure drop of 120 to 300 mbar, preferably 120 to 200 mbar.
- Figure 1 shows a process scheme known from the prior art of a large air separation plant for processing about 100,000 Nm 3 / h of air, in which it is necessary to implement the main heat exchanger by means of several separate heat exchanger blocks 3.
- Compressed and cleaned feed air 1 becomes part 2 directly several in parallel mutually arranged heat exchanger blocks 3a - 3e supplied, in part 4 by means of of a compressor 5 post-compressed, cooled in an after-cooler 6 and then into the Heat exchanger blocks 3a - 3e directed.
- This in the following as turbine air flow 7 designated compressed air is at an intermediate point the heat exchanger blocks 3a - 3e removed, relaxed in a turbine 8 and one in the low pressure column 10 Rectification unit 11, which has a pressure column 9 and a low pressure column 10 includes, initiated.
- the heat exchanger blocks 3a - 3e form the main heat exchanger of the Air separation plant.
- the supply air 2 cooled in blocks 3a - 3e becomes the Pressure column 9 of the rectification unit 11 supplied.
- the low pressure column 10 will gaseous oxygen 14, gaseous nitrogen 15 and gaseous impure nitrogen 16 taken as regeneration gas at a pressure of about 1.3 bar. Further it is possible to use oxygen and nitrogen as liquid in the rectification unit 11 Products 12, 13 to win.
- the gas streams 14, 15, 16 are in each of the Heat exchanger blocks 3a - 3e guided and against the feed air flow 2 and Turbine airflow 7 warmed by indirect heat exchange.
- FIG. 1 A method diagram corresponding to FIG. 1 is shown in FIG. in contrast to the known method shown in Figure 1, the Heat exchanger blocks 3 are divided according to the invention according to products.
- the Air flow 2 and the turbine air 7 are the same as in the method according to FIG 1 supplied to all heat exchanger blocks 23a - 23e.
- the gaseous Gas flows 14, 15, 16 no longer in all heat exchanger blocks 23, but in in each case specifically heated to the gas streams 14, 15, 16 blocks 23.
- the Heat exchanger blocks 23 are dimensioned so that the gaseous Oxygen stream 14 and the impure nitrogen stream 16 each have blocks 23a, 23e Result in maximum dimensions, i.e. blocks 23a and 23e are exactly on that expected oxygen or nitrogen amounts. From manufacturing technology For this reason, all blocks 23a-23e are executed with the same size, so that for the pure nitrogen flow 15, three heat exchanger blocks 23b-23d are required.
- the heat exchanger block 23a thus only oxygen 14 against the Air flows 2 and 7 guided through the blocks 23b to 23d pure nitrogen 15 against air 2, 7 and by the heat exchanger block 23e impure nitrogen 16 against air 2, 7. Die
- the number of heat exchanger blocks 23 thus remains in relation to the method Figure 1 the same, since the same product quantities with the same in both methods Air volumes have to exchange their heat.
- Every heat exchanger block 23 are only three streams, two air streams 2, 7 and a gas stream 14, 15 or 16, supplied, whereby each block 23 only six collectors / distributors with the appropriate connection piece required.
- the heat exchanger blocks 23 are in accordance with the figures 7 and 8 executed.
- the structure of a Heat exchanger blocks 3 shown the usual way.
- Figure 3 shows the Lamella arrangement in the distribution zones 31 for the oxygen passages 34, Figure 4 for the pure nitrogen passages 35 and Figure 5 accordingly for the Impure nitrogen passages 36.
- Figure 6 the arrangement of all inputs and Outlet nozzle to see.
- the distribution zones 31, 32, 33 both lead to a change in the direction of flow as well as cross-sectional changes, which in turn changes the Cause flow velocity. Both have a negative impact on the Block flow and creates an undesirable pressure drop across the Heat exchanger block 3.
- the pressure drop affects in particular the gas flows, which have a relatively low pressure between 1.1 and 1.8 bar.
- FIGS. 7 and 8 show the new block configuration.
- a key feature of the The inventive method is that in each heat exchanger block 23 only one of the gas streams 14, 15, 16 is guided in countercurrent with air 2, 7. With the End faces of the heat exchanger block 23 become collectors / distributors 43, also as Dome headers are referred to as inlets and outlets for the respective gas stream 14, 15, 16 connected.
- the collectors / distributors 43 are semi-cylindrical and have a connecting piece for the product feed or discharge.
- the one in the new Heat exchanger block 23 introduced gas flow does not experience anything Cross-sectional change and no significant change in current direction.
- the Pressure drop across the heat exchanger block 23 is greater than the pressure drop a usual block 3, as it was explained with reference to FIGS. 3 to 6, by approximately 30% reduced. Furthermore, the costs for the heat exchanger blocks 23 are reduced, since on the elaborate lamella cuts for the distribution zones 32 in Figures 3 to 5 can be dispensed with.
- the new Heat exchanger blocks preferably only have a narrow distribution zone 42 at the inlet and exit area of the heat exchange passages are provided.
- the slats in the narrow distribution zone 42 are parallel to the slats below or above the heat exchange passages are arranged, but have a smaller distance from each other.
- the gas entering the collector 41 easily builds up in front of the Distribution zone 42, which ensures an even distribution of the gas over all passages the distribution zone 42 and thus is reached on all heat exchange passages.
- FIGS Procedure Another advantage of the invention is shown in FIGS Procedure clearly.
- the piping in the new process much easier.
- the number of block sockets from ten to six per heat exchanger block are also fewer manifolds and Pipe bends necessary to block the gas flows 14, 15, 16 feed.
- the method according to the invention is not restricted to such processes only where all products are obtained in gaseous form, but also, for example Internal compression processes in which liquid products from the rectification unit subtracted from.
- Figure 9 shows the scheme of an air separation process in which in addition gaseous pure nitrogen 15 and gaseous impure nitrogen 16 liquid nitrogen 51 removed from the main capacitor of the rectification unit 11 and by means of an internal compression pump 52 is brought to increased pressure.
- the liquid and Nitrogen 51 brought to increased pressure is then in the heat exchanger block 56 against air 7 and compressed by the compressor 59 high pressure air evaporates and warmed up.
- the oxygen 12 is also in liquid form from the Low pressure column 10 is withdrawn and using the two pumps 54 and 55 internally compressed.
- the pure nitrogen stream 15 and the impure nitrogen stream 16 are in the heat exchanger blocks 23b, c, d and block 23e, respectively, respectively 7 and 8 are constructed, heated.
- internally compressed streams 57, 58 find a high-pressure heat exchanger block 56 Application.
- the high-pressure heat exchanger block 56 corresponds at first glance the heat exchanger block explained with reference to Figures 3 to 6, but has one significantly higher strength to withstand the high pressures of internal compression flows to be able to withstand. Those occurring in the heat exchanger block 56 Pressure losses have a far less effect on the internal compression flows 57, 58 negative than in the gaseous gas streams 15, 16 from the low pressure column 10.
- FIG. 10 A method similar to that in FIG. 9 is shown in FIG. 10, in which likewise liquid oxygen 12 is internally compressed 54, 55, but not against high pressure air, but is vaporized and heated against high pressure nitrogen.
- the Pressure column 9 removed gaseous nitrogen at 61 through which Heat exchanger block 62 out, compressed by means of the compressor 63 and in Countercurrent passed through the heat exchanger block 62 back into the pressure column 9.
- the construction of the heat exchanger block 62 corresponds essentially to that Heat exchanger block 56 in FIG. 9. There is no internal compression of nitrogen this variant, since 63 high-pressure nitrogen 64 are drawn off after the compressor can.
- FIG. 11 shows a further application of the method according to the invention.
- liquid oxygen is removed from the rectification column 11 at 12 and by means of the two pumps 54, 55 internally compressed.
- the evaporation of liquid oxygen takes place in this embodiment against circulating nitrogen, which at 61 from the Pressure column 9 removed, warmed in the heat exchanger block 77, with the compressors 71, 72, 73 compressed and in the heat exchanger block 77 against the Internal compression products cooled and passed into the pressure column 9 76.
- a part of the nitrogen is expanded after the compressor 71 (74) and into the Nitrogen cycle returned.
- Another part of the nitrogen is released Compression in compressors 71, 72, 73 and subsequent cooling in Heat exchanger block 77 at an intermediate point from the heat exchanger block 77 deducted, relaxed at 75 and returned to the nitrogen cycle.
