Abstract
The invention is an improvement in a vapor recovery system having a refrigeration system with two refrigerant compressors, a stack with a gaseous mixture flowing through it and a plurality of heat transfer units used to condense vaporized solvent which, along with a gas, is a constituent of the mixture. The improvement includes a heat exchange unit connected to the refrigeration system and disposed downstream of the heat transfer units. The heat exchange unit rejects heat from the refrigeration system to the gas, thereby reducing the input energy required by the refrigeration system.
