ABSTRACT:
Byproduct or waste gases, containing hydrogen fluoride, from an HF-catalyzed hydrocarbon alkylation process are contacted with a stream of liquid hydrocarbon essentially free from hydrogen fluoride. Hydrogen fluoride from the waste gases is recovered within the liquid hydrocarbon and is returned to the process therewith. Resulting waste gases are of reduced hydrogen fluoride content, and the recovery of hydrogen fluoride is thereby increased.
