Refrigerant recovery and purification method and apparatus with oil adsorbent separator

摘要

A refrigerant purification and recovery apparatus for removing refrigerant from a refrigeration unit and purifying the refrigerant includes refrigerant phase separation means for dividing a fluid refrigerant stream into a liquid phase and a gaseous phase stream, means for converting the liquid stream into a substantially gaseous stream and means for purifying the gaseous refrigerant stream including an oil polisher having a canister containing a porous, oleophilic, oil adsorbent material through which the refrigerant stream must pass.
