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.

A system for recovering fuel vapor during delivery of fuel by a mobile fueler includes a storage tank covered with a layer of insulation, a supply pump connected to the storage tank for delivering fuel therefrom, and a fuel dispensing assembly, preferably a coaxial hose and nozzle, including a supply outlet for delivering fuel to a vehicle being fueled, and a vapor recovery inlet proximate the supply outlet. A diverter valve diverts a portion of the fuel in the supply line, and a vacuum jet pump is connected to the storage tank and, by a vapor line, to the vapor recovery inlet, which is driven by the diverted fuel to create a vacuum in the vapor line to draw vapor into the vapor recovery inlet, through the vapor line, and into the storage tank.

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).
