ABSTRACT:
HF-containing vent gases, relief gases, CBM and polymers discharged from the alkylation zone of an HF alkylation process are contacted with water. Hydrogen fluoride is absorbed within the water, reacted with olefins, converted to organic fluorides and returned to the alkylation zone of the process. HF leaving the alkylation process in vent gases, relief gases, CBM and polymers is thereby recovered.
