Abstract:
1. A method for converting an HF alkylation unit which includes an HF settler to an ionic liquid alkylation system, the method comprising: a) providing an ionic liquid specific sub-system comprising an ionic liquid alkylation reactor and an ionic liquid coalescer; b) connecting the ionic liquid alkylation reactor to the HF settler for feeding an alkylation reactor effluent from the ionic liquid alkylation reactor to the HF settler, wherein the HF settler is configured for separating the alkylation reactor effluent into a hydrocarbon phase and an ionic liquid phase; and c) connecting the HF settler to the ionic liquid coalescer for feeding the hydrocarbon phase from the HF settler to the ionic liquid coalescer, wherein the alkylation reactor effluent is a homogeneous emulsion.
