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 system of fuel vapor recovery and use comprises a condensation module (10) that can connect to a fuel tank (2) of a service station by means of ventilation pipe (1), through which the fuel vapors are displaced to the cryogenic condensation module (10), wherein they are condensed, further comprising the cryogenic condensation module (10) and a return pipe (18) for the condensed vapors to the fuel tank (2), wherein that said cryogenic condensation module (10) comprises a cryogenic vaporizer (11) that lowers the temperature of the vapors by condensing them and a processing element (22) that processes the vapors that have not been condensed in said cryogenic vaporizer (11).

Methods and systems are provided for refueling a vehicle configured with an onboard refueling vapor recovery (ORVR) system, such that a loading of a fuel vapor canister configured to capture and store fuel vapors, is reduced. In one example, during the refueling, a rate at which fuel vapors are routed to the fuel vapor canister is adjusted responsive to an indication that the vehicle is refueling at a gas station equipped with offboard fuel vapor recovery infrastructure. In this way, loading of the fuel vapor canister may be reduced which may prevent undesired bleedthrough emissions resulting from a canister loaded with fuel vapors, particularly in examples where the vehicle is a hybrid vehicle and where engine runtime is limited, thus limiting potential opportunities for purging of the fuel vapor canister.

The spilled fuel collection system is configured for use with the fuel vent of a vessel. The fuel vent is designed to release gas and fuel during an event selected from the group consisting of: a) a build-up of gas pressure within the fuel tank; and, b) overfilling the fuel tank with fuel. The spilled fuel collection system is an accessory that captures fuel and fuel vapors that escape through the fuel vent of a vessel during the fueling process. The spilled fuel collection system comprises a transportable fuel container, a hose, and a quick connect fitting. The transportable fuel container captures the fuel and vapor that escape through the fuel vent. The hose transports the escaped fuel and vapor from the fuel vent into the transportable fuel container. The quick connect fitting secures the hose to the fuel vent.

A facility for storing and dispensing fuel, comprising: a storage tank (2) equipped with a vent pipe (3) and connected to a fuel dispenser (1) by a fuel dispensing system and by a vapor recovery system (10), and a condensation/separation device (4) connected to the vent pipe (3) and allowing fuel vapor originating from the storage tank (2) and water vapor originating from the outside air to be condensed,
characterized in that it comprises: at least one detection means (7, 8) cooperating with the condensation/separation device (4) for detecting the presence of condensed fuel and/or condensed water in said device and generating and transmitting a warning signal in response to said detection, and a control device (9) receiving said warning signal and transmitting, in response, information concerning the malfunction of the fuel vapor recovery system (10) to a control center (24).

A fuel drip retention system includes a computer programmed to actuate one of a pump or a starter motor to generate a vacuum in an evaporation line between a fuel nozzle receiving port and a vapor canister. The vacuum is generated upon determining that fuel has stopped flowing into a fuel tank.

A method for reducing emissions from a vessel includes isolating the vessel from a downstream fluid flow line, purging a fluid from the vessel by injecting purging media into the vessel to push the fluid through a check valve of a vent tubing and into the downstream fluid flow line, and draining the purging media from the vessel. A first end of the vent tubing is coupled to the housing of the vessel, and a second end of the vent tubing is coupled to the downstream fluid flow line. Further, the vent tubing includes a check valve disposed between the first end and the second end, and the check valve is configured to allow fluid to flow from the housing to the downstream fluid flow line.
