Abstract:
The invention is directed to a process and apparatus for recovering refrigerant from a refrigeration purge stream wherein a gaseous purge stream containing a refrigerant and non-condensible gasses is countercurrently contacted with a high boiling point liquid which absorbs the refrigerant from the purge stream. Preferably a scrubbing column is used to effect countercurrent contact between the purge stream and the liquid stream.
