Reducing acid consumption: Maximizing sulfuric acid alkylation unit profitability

Alkylation is a process used to produce highly branched isoparaffins from the reaction of lighter olefins and isobutane in the presence of sulfuric acid as a catalyst.

Alkylation is a process used to produce highly branched isoparaffins from the reaction of lighter olefins and isobutane in the presence of sulfuric acid as a catalyst. This highly branched isoparaffin is called alkylate—a blending component that constitutes approximately 10%–15% of the gasoline pool in the U.S. Besides the ability to increase octane and lower Reid vapor pressure (RVP) in the gasoline pool, alkylate also reduces vehicle exhaust emissions with zero olefins, zero aromatics and low sulfur. Alkylate margins have been very healthy worldwide over the past 10 yr. The gross margins (alkylate value minus feedstock cost) for the U.S. Gulf Coast have ranged from a low of about $20/bbl
