HEAT AND LIQUID RECOVERY USING OPEN CYCLE HEAT PUMP SYSTEM

摘要

Heat and / or condensable liquid recovery from a gaseous medium by using an open cycle heat pump system. The open cycle heat pump system is used to modify the temperature of a gas by compression (1), expansion (5), heat exchange (3), and their combination, to condense desired vapors carried in the medium gas to separate them from gas. The open cycle heat pump system can also be used to extract heat from a gas. It is also concerned with the recovery of a condensable solvent and / or gas stream heat used in drying ovens (41) which are used in the treatment of solvent laden material.
