Refrigeration process with purge and recovery of refrigerant

摘要: A refrigeration process including a cycle, and refrigerant purge recovery operations is disclosed. The cycle may be vapor compression or an absorption for example. stream withdrawn from the subjected to treatment by means of membrane separation unit. purge-stream operation produces essentially pure stream, suitable return air clean enough direct discharge atmosphere. applicable most refrigerants, but particularly useful in minimizing atmospheric emissions chlorofluorocarbons, such as CFC-11 CFC-12.
