Abstract
The systems and methods of fuel vapor recovery and use comprise a cryogenic condensation module and a fuel tank of a service station. The cryogenic condensation module comprises a cryogenic vaporizer that lowers the temperature of fuel vapors via condensation. The cryogenic condensation module also comprises a processing element that processes the fuel vapors that have not been condensed via the cryogenic vaporizer. The fuel tank is connected to the cryogenic condensation module by a ventilation pipe and a return pipe. The ventilation pipe is capable of displacing the fuel vapors to the cryogenic condensation module. The return pipe is capable of returning condensed fuel vapors to the fuel tank.
Claims20
A system of fuel vapor recovery and use, the system comprising:
- a fuel tank of a service station, the fuel tank connected to a cryogenic condensation module by a ventilation pipe and a return pipe, wherein the ventilation pipe displaces fuel vapors to the cryogenic condensation module, and wherein the return pipe returns condensed volatile elements of the fuel vapors to the fuel tank;
- and
- the cryogenic condensation module comprising:
- a cryogenic vaporizer having a first module that fractionally condenses water vapors and a second module that fractionally condenses the volatile elements of the fuel vapors that are more volatile than the water vapors, wherein the first module and the second module are at different temperatures;
- and
- a processing element having a coalescing mesh, wherein the processing element processes the fuel vapors that have not been condensed via the cryogenic vaporizer, and wherein the coalescing mesh is positioned in a series with the first module and the second module.
A method of fuel vapor recovery and use comprising:
- receiving, at a cryogenic condensation module comprising a cryogenic vaporizer and a processing element positioned in a series with a first module and a second module of the cryogenic vaporizer, fuel vapors comprising volatile elements and water vapors, wherein the fuel vapors were received from a fuel tank via a ventilation pipe;
- fractionally condensing, via the first module of the cryogenic vaporizer, the water vapors;
- fractionally condensing, via the second module of the cryogenic vaporizer, the volatile elements, wherein the first module and the second module are at different temperatures;
- processing, via the processing element, the fuel vapors that have not been condensed via the cryogenic vaporizer;
- and
- returning the volatile elements that were condensed to the fuel tank via a return pipe.
A process for isolating volatile elements of fuel vapor for fuel recovery and use, the process comprising:
- receiving fuel vapors at a cryogenic condensation module via a ventilation pipe connected to a fuel tank, the fuel vapors comprising water vapors and volatile elements, the cryogenic condensation module comprising:
- a cryogenic vaporizer that lowers a temperature of fuel vapors via condensation, the cryogenic vaporizer having a first module and a second module;
- and
- a processing element positioned in a series with the first module and the second module of the cryogenic vaporizer;
- fractionally condensing, via the first module, the water vapors;
- fractionally condensing, via the second module, the volatile elements, wherein the first module and the second module are at different temperatures;
- processing, via the processing element, the fuel vapors that have not been condensed;
- and
- returning the volatile elements that were condensed to the fuel tank via a return pipe.
