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 absorbed within the liquid hydrocarbon and is returned to the process therewith. Resulting waste gases are of reduced hydrogen fluoride content, and the loss of hydrogen fluoride upon disposal of these gases is thereby reduced.
