Definitions
- the present invention relates to a process for the treatment and / or recovery and / or recycling of residues, in particular from refinery processes, which contain a base substance, in particular with hydrocarbon, such as kerosene, and oil and metallic residues.
- a base substance in particular with hydrocarbon, such as kerosene, and oil and metallic residues.
- residues arise, which consist for example of hydrocarbons, oil and metals. All three components are too valuable for them to be disposed of easily.
- the largest sources of residues with hydrocarbons are eg petroleum refining processes. These include atmospheric distillation, vacuum distillation, production of fuel oil and fuels, alkylation with sulfuric acid, polymerization of a mixture of propene and butane with phosphoric acid, high temperature isomerization, production of lubricating oils, rectification, tube distillation, boiling distillation, coking, catalytic cracking, reforming , Refinery hydrogenation,
- the petrol content accounts for most of the petroleum products and is subdivided according to their intended use: specialty fuels, motor gasoline, jet fuel, jet fuel, heavy fuel, kerosene, lamp oil, diesel fuel, heating oil, oils (motor, aircraft, turbine oil, insulating oil, hydraulic oil, metal working oil , medical, etc.).
- only those coolants or lubricants for machine tools which are used in production processes are to be mentioned. This is a large amount of residues, which include hydrocarbons, oils and metallic residues.
- JP 09-109144 describes a method for fractionating a machining suspension in which kerosene is first fed to the machining suspension as an extraction agent for lowering the viscosity, in order to separate the cutting grain from the cooling lubricant in a wet classification process. This document is about the clean separation of the cutting grain from the cooling lubricant, but not the recovery of the cooling lubricant in high quality form, as required for example for reuse in sawing.
- Object of the present invention is to provide a method of the above type, with which refinery residues, which contain in particular kerosene, oil, asphaltenes and metals, can be worked up effectively and economically.
- the product is discharged in this case usually as a melt from the reactor. However, the product is particularly preferably transferred to a second reactor where it is solidified or granulated by cooling and optionally evaporative cooling.
- Mixing kneaders are preferably used as reactors. Essentially, single-shaft and twin-shaft mixing kneaders are distinguished.
- a single-shaft mixing kneader is known, for example, from AT 334 328, CH 658 798 A5 or CH 686 406 A5.
- an axially extending, occupied with disc elements and rotating about a rotational axis in a rotational direction shaft is arranged in a housing. This causes the transport of the product in the transport direction. Between the disc elements counter elements are fixedly mounted on the housing. The disc elements are arranged in planes perpendicular to the kneader shaft and form between them free sectors, which form with the planes of adjacent disc elements Knüschreib.
- a multi-shaft mixing and kneading machine is described in CH-A 506 322.
- a mixing kneader of the abovementioned type is known, for example, from EP 0 517 068 B1. With him turn in a mixer housing two axially parallel shafts either in opposite directions or in the same direction. In this case, mixing bars applied to disk elements interact with each other. In addition to the function mixing, the mixing bars have the task of cleaning product-contacted areas of the mixer housing, the shafts and the disk elements as well as possible and thus avoid unmixed zones. Particularly in the case of strongly compacting, hardening and crusting products, the randomness of the mixing bars leads to high local mechanical loads on the mixing bars and the shafts. These force peaks occur in particular when engaging the mixing bars in those zones where the product can escape badly. Such zones are given, for example, where the disc elements are mounted on the shaft.
- a mixing kneader og. Art in which the support elements form a recess in the region of the kneading bars, so that the kneading bar has the largest possible axial extent.
- Such a mixing kneader has excellent self-cleaning of all product-contacting surfaces of the housing and the waves, but has the property that the support elements of the kneading bars due to the paths of the kneading bars make recesses necessary, which lead to complicated Tragelementformen.
- a mixing kneader is fundamentally different from an extruder. Whereas a screw rotates in an extruder in a corresponding tubular casing shell and thus conveys the product to be treated from an inlet to an outlet in the screw flights, a product space and a gas space are formed in a mixing kneader.
- the product space is, as the name says, filled with product, the gas space, which is usually located above the product space, fills in the treatment of the product with gas, which then deducted by appropriate vapors.
- An actual treatment of the product namely a mixing and kneading and transporting takes place only in the product space, the gas space is free of product.
- the first process stage may also be a mixing kneader without hooks, a thin-film evaporator or paddle dryer used.
- a mixing kneader without hooks may also be a mixing kneader without hooks, a thin-film evaporator or paddle dryer used.
- a cooling roller, a cooling belt or a solution with water basin or conveyor under water are conceivable in addition to the mixing kneader.
- the various combinations of the various options for the two process stages should also be included in the inventive concept.
- the present process uses by way of example the above-described two-stage process with two mixing kneaders, the residues to be worked up passing through these mixing kneaders in succession.
- the process presented here may include other process steps, such as Washing or premixing the residues with solvent, upstream.
- a different mixture of solid residues, residual oils and solvents resp. volatile components In experiments it was found that in the first step, the evaporation of the solvent resp. the volatile constituents, the heat transfer coefficient is significantly higher, the more residual oil is present. This leads to an acceleration and overall improvement of the process.
- the introduction of the homogenized residues in the first mixing kneader is preferably carried out by means of a pump and specifically by means of an eccentric screw pump, as it is known under the trade name Moyno pump.
- a pump namely the gear pump
- the gear pump has proven to be extremely unfavorable, since it tends to clog when the feed supply (residue supply) is too irregular.
- the inlet should also be cooled in the first mixing kneader, otherwise it tends to clog at a feed interruption. This is especially true when the residues are not flashed, ie, not introduced under pressure in the mixing kneader.
- the filling level or filling level in the mixing kneader (s) is regulated by an adjustable weir. As a result, a more suitable control of the entire process takes place.
- the treatment of the residues can take place both atmospherically and under vacuum in the first mixing kneader.
- the treatment of the product takes place with addition of heat and also under friction.
- Will solvents resp. readily volatile constituents which ignite easily, e.g. Kerosene, should be avoided penetration of oxygen into the mixing kneader.
- the transfer of the product from the first mixing kneader into the second mixing kneader preferably takes place via a flexible conduit which can be heated, but optionally can also be cooled.
- the inlet of the second mixing kneader should be able to be heated.
- a suitable sleeve is provided.
- the second mixing kneader In the second mixing kneader, a transfer of pasty residues coming from the first mixing kneader into the solid phase takes place by cooling, so that solids are present at the discharge. However, these also have a relatively large amount of dust, so that at least one lock container should be connected downstream of the second mixing kneader.
- water can optionally also be introduced into the second mixing kneader, which evaporates and thus promotes cooling (evaporative cooling).
- Protection is also desired for a corresponding plant for working up residues described above, in which a first mixing kneader is followed by a second mixing kneader, wherein both mixing kneaders are connected to each other by a heatable line. Further attention-related features are described above.
- This residue R is preferably subjected to one or more pretreatments 1, e.g. a washing or homogenization process.
- pretreatments 1 e.g. a washing or homogenization process.
- foreign components can be largely eliminated.
- the pretreated residues are now transferred to a receiving hopper 3, before they are transferred by means of a pump 4 in a first mixing kneader 5.
- the pump 4 is preferably a Moyno pump, which is understood to mean a throat eccentric screw pump. Trials with a gear pump failed.
- the transfer into the first mixing kneader takes place via an inlet 6, which is preferably cooled. This should be done especially if no additional flash nozzle is used, with which the residues under pressure in the first IVlischkneter be introduced. Without cooling the inlet there is a risk of blockages, especially when the supply is interrupted.
- a weir 9 is provided in front of a discharge 8 in the first IVlischkneter, which is adjustable in height. This weir 9 should also be heated and serves to control a level of fill in the first mixer.
- the transfer of pasty residue from the first IVlischkneter to a second IVlischkneter 10 is effected by a dashed line indicated 1 1, which is preferably flexible and heatable. However, it is also provided to assign this line 1 1 a cooling device 12.
- an inlet 13 in the second IVlischkneter 10 should be heated, whereby the transfer of pasty residue in the second IVlischkneter 10 is facilitated.
- water can also be entered into the second mixer. This water promotes the solidification of the residues and dissipates heat during evaporative cooling. Furthermore, it helps on a case by case basis to discharge an oil. At a discharge 15 of the second mixing kneader 10 are free flowing solids. However, a lot of powder in the solidified residue is present, so that it proves advisable to connect to the discharge 15 at least one lock container 1 6.
- the transfer of the residue from the first mixing kneader into the second mixing kneader takes place through the heated flexible line 11.
- the heating takes place at about 210 ° C.
- the second mixing kneader Depending on the feed rate of the second mixing kneader is filled with the pasty material to a maximum of about 60% level.
- the treatment of the residue is carried out here optionally with the addition of water, which dissipates heat by evaporative cooling.
- the residues are present as free-flowing solids.
- a further exemplary procedure is as follows:
- the mentioned mixture of solvent and solids comes in the first process stage in a mixing kneader (with hooks), where the solvent is evaporated.
- the solids - if necessary with the addition of Water for evaporative cooling - cooled in a mixing kneader with hooks, solidified and granulated.
- solvent or residual oil or water (if added) is also evaporated in the second process step. stripped ..
- the separation of the process in two stages is necessary because the necessary process parameters (especially the temperatures) for evaporation of the solvent, respectively. for granulation of the solids are too far apart than a process stage would be sufficient. Therefore, conventional single-stage drying processes are out of the question.
- protection is also sought for a one-step process. In this case, the solidification is eliminated, and after the evaporation stage, a melt is discharged.
