ABSTRACT:
A system for recovering and refining volatile liquids such as refrigerants includes a suction accumulator which serves as a precleaning module. The accumulator has an intake for contaminated fluids. A compressor having a suction side thereof is connected to the suction accumulator, while a discharge side thereof is connected to a condenser which, in turn, delivers the condensed liquid gas to a collector tank. A filter removes contaminants from the fluid flow in the connection between the suction accumulator and the collector tank. Precleaning of the intake fluid in the suction accumulator is accomplished by cold surface distillation to remove contaminants. Efficient distillation of the intake fluid is achieved from the beginning of the recovery of the volatile fluid by diffusing the incoming fluid over a cold surface of an evaporating refrigerant provided as a precharge in the suction accumulator.
