A system and/or process for removing water from an alkylation catalyst mixture of an alkylation process is disclosed. The process includes passing an alkylation reaction zone effluent to a settler for separation into a hydrocarbon phase and a catalyst mixture phase; passing at least a portion of the hydrocarbon phase, as a settler effluent stream containing alkylate, water, HF and volatility reducing additive, to a first separator; removing and condensing a first overhead stream from the first separator thereby forming an HF/water stream; passing the HF/water stream to a second separator for separation into a modified HF stream containing HF and volatility reducing additive and into an HF/water azeotrope stream containing HF and water; using the modified HF stream as a part of the alkylation catalyst mixture and; removing water from the system by removing the HF/water azeotrope stream from the second separator.
