Alkylation Process

Olefins and isobutane are dried and fed to a reactor, where the alkylation reaction takes place over the HF catalyst. The reactor effluent flows to a settler, where the acid phase separates from the hydrocarbon phase. The acid is drawn off and recycled. The hydrocarbon phase goes to a deisobutanizer (DIB).

Alkylation | FSC 432: Petroleum Refining

Alkylation . The alkylation process combines light iso-paraffins, most commonly isobutane, with C 3 –C 4 olefins, to produce a mixture of higher molecular weight iso-paraffins (i.e., alkylate) as a high-octane number blending component for the gasoline pool. Iso-butane and C 3 –C 4 olefins are produced as by-products from FCC and other catalytic and thermal conversion processes in a refinery.
