Abstract
Vent gases containing propane and HF obtained from a hydrocarbon alkylation operation are treated together with an alkylate either before or after it has been debutanized thus to remove HF from said vent gases and/or the vent gases are combined with a normal butane stream before it is treated to remove HF therefrom thus to remove HF from said vent gases. In any event described, the propane in the vent gases is advantageously recovered in the normal butane containing stream.
