Abstract

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.
