An alkylation unit (alky) is one of the conversion processes used in petroleum refineries. It is used to convert isobutane and low-molecular-weight alkenes (primarily a mixture of propene and butene) into alkylate, a high octane gasoline component. The process occurs in the presence of an acid such as sulfuric acid (H2SO4) or hydrofluoric acid (HF) as catalyst. Depending on the acid used, the unit is called a sulfuric acid alkylation unit (SAAU) or hydrofluoric acid alkylation unit (HFAU). In … WebAlkylation processes transform small olefin and iso-paraffin molecules into larger iso-paraffins with a high octane number. Combining cracking, polymerization, and alkylation can result in a gasoline yield representing 70 percent of the starting crude oil.
