This disclosure relates to methods of converting an HF alkylation unit which utilizes HF as a reaction catalyst to a sulfuric acid alkylation unit which utilizes sulfuric acid as a reaction catalyst. This disclosure also relates to a segmented sulfuric acid settler for separating a sulfuric acid phase from a hydrocarbon phase. This disclosure also relates to methods of converting a vertical HF acid settler to a segmented sulfuric acid settler. This disclosure also relates to converted sulfuric acid alkylation units and alkylation processes performed in the converted sulfuric acid alkylation units.
A method for converting a hydrogen fluoride alkylation unit which utilizes hydrogen fluoride as a reaction catalyst to a sulfuric acid alkylation unit, the hydrogen fluoride alkylation unit comprising an HF alkylation reactor, an HF alkylation fractionation section comprising at least one fractionator, and an HF acid relief neutralizer vessel, the method comprising:
A segmented sulfuric acid settler for separating a sulfuric acid phase from a hydrocarbon phase, the sulfuric acid settler comprising:
A method for converting a vertical HF acid settler to a segmented sulfuric acid settler, the vertical HF acid settler comprising a vertical vessel having an outlet at its top section, a vertical interior wall, a bottom, and an internal baffle extending upwardly from the bottom of the vertical vessel, the method comprising:
A method for converting a vertical HF acid settler to a segmented sulfuric acid settler, the vertical HF acid settler comprising a vertical vessel having an outlet at its top section, a vertical interior wall, a bottom, and internal components comprising an internal baffle extending upwardly from the bottom of the vertical vessel, the method comprising:
