ABSTRACT:
Byproduct or waste gases, containing hydrogen fluoride from an HF-catalyzed aromatic alkylation process are contacted with a stream of alkylated aromatics essentially free from hydrogen fluoride. Hydrogen fluoride from the waste gases is absorbed within the alkylated aromatics 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.
