Process details
Sulfuric acid alkylation process in the oil & gas industry
Feed of propene and butene monitoring
The lighter oils originating from the lower parts of the distillation column, after passing through Hydrotreaters and the Fluid Catalytic Cracker (FCC), produce low-molecular-weight alkenes (butenes (C4), pentenes (C5), propene (C3H6)) and also isobutene (C4H10). The acid alkylation process converts these streams into alkylate, a high octane and clean burning gasoline blending component. Depending on the acid used, the process is called either SAA (Sulfuric Acid Alkylation) or HFA (Hydrofluoric Acid Alkylation).
