ABSTRACT:
A method and apparatus are disclosed for separation of non-condensible gas from recovered refrigerant collected in a collector tank. Non-condensible gas is intermittently vented from the collector tank. The vented non-condensible gas is directed to an accumulator which processes the vented non-condensible gas in a manner which allows gravity separation of the non-condensible gas from refrigerant liquid and vapor which may be mixed therewith in the vented gas from the collector tank. The gravity separated non-condensible gas and refrigerant in the accumulator are removed from the accumulator through respective outlets in the accumulator. The refrigerant is recycled in a refrigerant recovery apparatus and the gravity separated non-condensible gas is released to the atmosphere. The method and apparatus reduce release of refrigerant to the atmosphere as a result of venting of the collector tank.
