Hf alky unit
WebAlkylation unit Also known as: alky In refining, the alkylation unit produces a high-quality gasoline blendstock by combining two LPG -range molecules to form one gasoline-range molecule. This involves reacting isobutane with some type of light olefin, typically either propylene or butylene coming from the FCC. WebHydrofluoric Acid (HF) Alkylation Units, often referred to as HF Alky units, are process units used in petroleum refining to convert isobutane and alkenes (primarily propylene or butylene) into alkylate, which is used to make gasoline.

WebWhen ASO is removed, significant amounts of alkylation catalyst (HF or H 2 SO 4) leave with it. ASO is hazardous and difficult to dispose of properly; a high ASO amount means yield and catalyst loss. Alkyfining® solves these problems producing some very attractive results. Alkyfining® is the market leader for upgrading alkylation plant feeds. WebHydrofluoric Acid (HF) Alkylation Units Olefins (C3-C4) from the FCC unit are combined with isobutane (i-C4) and are first treated with a mol sieve bed to remove water. Concentrated HF is then mixed in and fed to the reactor.
