Safe and sustainable alkylation for the forward-looking refiner

WebA process for producing alkyl aromatics using a transalkylation reaction zone and an alkylation reaction zone is disclosed. One portion of the transalkylation reaction zone effluent passes to an alkylation reaction zone where an aromatic substrate is alkylated to the desired alkyl aromatic. At least a portion of the alkylation reaction zone effluent and … WebBalasubramanian Viswanathan, in Energy Sources, 2024. Alkylation. Alkylation is the transfer of an alkyl group from one molecule to another. The alkyl group may be transferred as an alkyl carbocation, a free radical, or a carbanion. In a standard oil refinery process, alkylation involves low–molecular weight olefins (primarily a mixture of propylene and … tendon kohaku burnaby bc

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 … Zobraziť viac 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 equal share of 800,000 barrels per day for SAAU and HFAU technologies. On … Zobraziť viac The availability of a suitable catalyst is also an important factor in deciding whether to build an alkylation plant. Sulfuric acid Zobraziť viac The catalyst protonates the alkenes (propene, butene) to produce reactive carbocations, which alkylate isobutane. The reaction is carried out at mild temperatures (0 … Zobraziť viac 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 … Zobraziť viac 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 … Zobraziť viac HFAU process description The HFAU can be divided into three main sections: reaction, fractionation, and defluorinating / alumina treating. The purpose of the unit is to react an olefin feed with isobutane in the reaction section in the … Zobraziť viac Maintenance costs and data are difficult to obtain on a comparable basis. HFAU have much more peripheral equipment (feed driers, product treaters, acid regeneration column and an acid-soluble oil neutralizer), thus more pieces of equipment to … Zobraziť viac tendon kohaku burnaby hiring

"Web5. máj 2024 · Alkylation typically uses a catalyst such as sulfuric acid or HF to create high-octane gasoline. However, the use of HF has been associated with explosions at refineries.
