Feed Purification

Butadiene makes unwanted high boiling oligomers often called sludge or ASO (Acid Soluble Oils). When ASO is removed, significant amounts of alkylation catalyst (HF or H₂SO₄) 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. By converting butadiene to butenes (for higher alkylate octane) Alkyfining® greatly enhances alkylation plant performance.

With respective Alkyfining® market shares of 70% and 95% of the HF and H₂SO₄ alkylation feed pretreatment plants, Axens is the world’s leading player in alkylation plant feed pretreatment.
