Abstract
The invention is an improvement in an apparatus for condensing and recovering vaporized solvent entrained with a gas. Such apparatus has a multistage refrigeration system including a high stage circuit with a high pressure refrigerant conductor. The inventive improvement includes a solvent heat exchanger with a vessel for containing very cold condensed solvent. A portion of the high pressure refrigerant conductor is in heat-exchange relationship to such condensed solvent and transfers heat to such solvent, thereby increasing the refrigerating capacity of the system.
