The HF process only creates a small amount of organofluorine side products which are continuously removed from the reactor and the consumed HF is replenished. See more 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 … See more The availability of a suitable catalyst is also an important factor in deciding whether to build an alkylation plant. Sulfuric acid See more The catalyst protonates the alkenes (propene, butene) to produce reactive carbocations, which alkylate isobutane. The reaction is carried out at mild temperatures (0-30 °C) in a two-phase reaction. Because the reaction is exothermic, cooling … See more Refineries examine whether it makes sense economically to install alkylation units. Alkylation units are complex, with substantial economy of scale. SAAU and HFAU have comparable capital investment costs. It is not surprising that the two processes are … See more The first alkylation units entered in service in 1940. In 2009 around 1,600,000 barrels per day of capacity were installed worldwide, with an … See more The olefin feed to an alkylation unit generally originates from a FCCU and contains butene, isobutene, and possibly propene and/or amylenes. The olefin feed is also likely to contain diluents (such as propane, n-butane, and n-pentane), noncondensables … See more HFAU process description The HFAU can be divided into three main sections: reaction, fractionation, and defluorinating / alumina treating.
