Definitions
- the invention relates to a device for the separation of gasoline vapors at atmospheric pressure by means of a solvent, e.g. Diesel oil, wherein a gasoline-containing tank is connected to a scrubber via a pipe, and the hydrocarbons contained in the gasoline, e.g. Butane, to be returned to the tank.
- a solvent e.g. Diesel oil
- a gasoline-containing tank is connected to a scrubber via a pipe, and the hydrocarbons contained in the gasoline, e.g. Butane, to be returned to the tank.
- This device serves to keep the toxic gasoline vapors escaping during the refueling process away from the environment and back into the tank.
- the device consists in that the tank containing gasoline forms a part of a circulatory system by means of an exhaust steam line containing a packing or a scrubber, further comprises a pump, a charging institute for the solvent, a reversing vessel with a saturation control agent and circulation pipelines, and a return line in the tank and has a discharge pipe.
- US Pat. No. 2,849,150 A describes a system for recycling vapors.
- vapors are collected in an expansion vessel and fed on reaching a defined pressure via a compressor of a pressure-swing condenser.
- the absorbate from the wash column and pressure condensation plant is fed back to the washing medium tank (gas storage tank).
- this training does not apply to the subject of the application
- the present invention seeks to provide a simple means for the separation of gasoline vapors, in which the return of gasoline vapors takes place in the tank and can be retrofitted to existing systems.
- the object is achieved in that the scrubber, to which gasoline vapors can be introduced from the tank through a duct, and a vessel for the absorbate, i. a mixture of diesel oil with the absorbing hydrocarbons is connected by means of a loop in which a pump for the circulation of the solvent is arranged, wherein the container for the absorbate is connected by stop valves in the loop system via a line and has a connection for a return, in which a vacuum pump is arranged, with a return pipe in the tank.
- a vessel for the absorbate i. a mixture of diesel oil with the absorbing hydrocarbons
- the container for the absorbate is connected by stop valves in the loop system via a line and has a connection for a return, in which a vacuum pump is arranged, with a return pipe in the tank.
- the scrubber and / or the vessel contain expanded particles formed from expanded material. This gives you the opportunity to process the hydrocarbon components and return them to the tank.
- the scrubber to which gasoline vapors from the tank can be introduced through a pipe, and two vessels for the absorbent are connected in parallel by means of a ring pipe in which a pump for a circulation of the solvent is arranged, one vessel in each case Shut-off valves is separated in the ring system and in each case by an open valve having a connection for a return, in which a vacuum pump is arranged, with a return pipe into the tank.
- This is important so that the individual vessels do not interfere with each other in the reciprocal sequence of the return of hydrocarbon fractions.
- the reaching into the tank return pipe extends to close to the tank bottom, optionally includes a deflection in the horizontal position and is designed as a tunnel-like shaft. The purpose of this is that the separated gas bubbles of hydrocarbons can escape under the tank level.
- tunnel-like shaft is filled with known fillers of expanded material and optionally inclined at an acute angle from the horizontal plane upwards. As a result, the rising of the gas bubbles is favored and these distributed get into the gas tank.
- the container (s) for the absorbate is (are) formed in each case of at least two individual vessels arranged in series, which individual vessels may have a heating device, e.g. Heating coil or a cooling device, e.g. a cooling coil.
- a heating device e.g. Heating coil
- a cooling device e.g. a cooling coil
- FIG. 1 the structure of the device is shown schematically.
- a tank 1 with indicated triangle of the gasoline level is given as an example.
- the return pipe 3 extends to the tank bottom 5 and contains at the end of a tunnel-like shaft 4, which is arranged on the vertical return pipe 3 approximately in a horizontal position, but inclined at an acute angle a upwards, is attached.
- the tunnel-like shaft 4 is filled with expanded material 10 and below, so the tank bottom 5 out and the output side open.
- a per se known gas scrubber 6 includes a supply line 7, which leads from the filler neck 2 in the tank 1.
- the supply line 7 is connected to the lower part of the scrubber 6, and at a certain distance from the ground, so that just a small liquid level of diesel oil in the scrubber 6 remains, for example, marked with a triangle.
- the scrubber 6 itself is filled with expanded material 10.
- a ring line 11 leads from the bottom of the vessel 9 up to the top, lateral location of the scrubber 6. An opening at the top of the scrubber 6 serves to discharge the air.
- a pump 14 is disposed in the loop 11.
- a shut-off valve 12 is arranged on the input side in the region of the vessel 9, and a further valve 13 on the output side.
- the vessel 9 Up to a certain level - indicated by a triangle - the vessel 9 is filled with diesel oil. Further, the return line 8 is connected to the top of the vessel 9. With the aid of a vacuum pump 15, which is arranged in the return line 8, the gas mixture is returned via return tube 3 into the tank 1.
- Fig. 2 shows a further variant of the device according to the invention.
- a tank 1 which, for example, with gasoline - indicated by a triangle - is filled.
- a vertical return pipe 3 is mounted, which extends with its tunnel-like shaft 4 to the tank bottom 5.
- the scrubber 6 is arranged above in the drawing and connected via ring line 11 with associated pump 14 to the vessel 9.
- Another vessel 19 is parallel to the vessel 9 via a connecting line 17 switched, connected.
- For the vessel 9 serve the shut-off valves 12 and 13, while the shut-off valves 20 and 21 are provided for the vessel 19.
- the return line 8 contains for each vessel 9, 19 a shut-off valve 18 and 19.
- This arrangement now has the advantage that one vessel, for example, the vessel 9 maintains the circulation, while the other vessel, eg vessel 19, the hydrocarbon fractions in the tank conveyed back.
- An interruption of the return promotion can not occur in this arrangement variant, as always one vessel provides for the return promotion and the other maintains the circulation.
- FIG. 3 shows a development of the vessels 9, 19 in order to increase the efficiency. It shows, for example, a vessel containing filler 10 in a known manner and up to 4/5 of its capacity with diesel oil - indicated by a triangle - filled. Above and below now the ring line 11 is provided, which can be interrupted by means of shut-off valves 12, 13. Around the vessel 9, 19 is a heater, e.g. Heating coil 23 is arranged. Thus, the evaporation process is significantly favored.
- Fig. 4 shows in a similar manner as already described in Fig. 3, a vessel 9, 19, but instead of the heating means a cooling device, e.g. a cooling coil 24 contains. Again, the evaporation process is favored.
- a cooling device e.g. a cooling coil 24 contains. Again, the evaporation process is favored.
- the return pipe 3 is listed at the lower part near the tank bottom 5, wherein the tunnel-like shaft 4 is fixed at an acute angle a upwards from the horizontal plane. Inside the tunnel-like shaft 4, the expanded material 10 is attached. This will split the gas bubbles to better absorb the gas.
