Conversion of HF alkylation units for ionic liquid catalyzed alkylation processes

摘要

Methods for converting an HF alkylation unit to an ionic liquid alkylation system configured for performing ionic liquid catalyzed alkylation processes may comprise connecting at least one component configured for ionic liquid catalyzed alkylation to at least one component of the HF alkylation unit, wherein the at least one component of the HF alkylation unit is retained, modified or adapted for use in the ionic liquid alkylation system. An ionic liquid alkylation system derived from an existing or prior HF alkylation unit is also disclosed.

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.
