A purge system operable to remove lubricant from a liquid refrigerant material removed from an evaporator of a mechanical refrigeration system. The contaminated liquid refrigerant is delivered to the purge system by gravity and the separated lubricant is returned to the compressor sump by force from a pressurized fluid. Refrigerant vapor is separated from the contaminated liquid refrigerant by heating and returned to the evaporator of the mechanical refrigeration system.
