Reducing Reactor Temperatures In Sulfuric Acid Alkylation Units

Description:

As operators of Sulfuric Acid Alkylation units know, lower reactor temperatures are preferred. Lower reactor temperatures reduce corrosion and acid consumption, while increasing alkylate octane. In addition, high-temperature constraints often limit alkylate production rates. This paper reviews the economic case for reducing reactor temperatures, as well as cost-effective ways this can be accomplished. Several examples of recent successes in this area are also provided.
