Web27. okt 2024 · Alternative alkylation technologies have been developed, such as a solid acid catalyst and new ionic liquid acid catalyst alkylation technology. Replacing highly toxic chemicals with less hazardous chemicals is an “inherently safer design” approach. Additionally, some refinery alkylation units use sulfuric acid as a catalyst instead of HF. WebThe control strategies presented provide effective advanced regulatory control of the reactors and the distillation towers associated with HF and sulfuric acid alkylation units. Reactor isobutane/olefin ration, thruput and temperature are the major control variables in the reactor section.
WebIn oil refining contexts, alkylation refers to a particular alkylation of isobutane with olefins. It is a major aspect of the upgrading of petroleum.

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 …
WebThe traditional designs of alkylation unit use either hydrofluoric or sulphuric acids as the catalyst. Over the past 10 years, issues with the safety and risks associated with large inventories of HF in refineries have been examined and understood. Web17. apr 2024 · And there’s another wrinkle: Sulfolane can prevent alkylation units, which are integral in the conversion process from crude oil to high quality gasoline, from properly functioning. According to Hayati, in 1997 the additive caused the MHF unit to malfunction, and the Torrance refinery reverted back to using HF.
