ABSTRACT:
A refrigeration purge system comprising a purge drum coupled to receive purge gas from a primary refrigeration system. The purge gas includes a primary refrigerant component and a noncondensable component. The purge system also includes a secondary refrigeration system which uses a secondary refrigerant. The secondary refrigerant and the purge gas are passed in heat exchange relationship in the purge drum to condense the primary refrigerant component of the purge gas. The condensed primary refrigerant is then returned to the primary refrigeration system, and the noncondensable component is expelled from the purge drum.
