A Vapor Recovery Unit (VRU) includes a VRU heat exchanger and a sorbent material for the recovery of hydrocarbon vapors from the ullage of tanks. The VRU heat exchanger and sorbent material are useful in conjunction with a thermal transfer fluid to control the temperatures of the sorbent material during endothermic and exothermic reactions that occur when hydrocarbon vapors are adsorbed and desorbed, which increases performance and reduces the amount of sorbent material required to recover hydrocarbon vapors.

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.
