ISOALKY™

First used in Chevron’s Salt Lake City refinery, ISOALKY^™ technology is designed to meet the refining industry’s needs for a cost-effective alternative to conventional liquid acid systems that offers process safety advantages.

Using a non-aqueous liquid salt, or ionic liquid, the revolutionary new catalytic process is handled with standard personal protective equipment and produces a valuable high-octane blending component that helps lower the environmental impact of gasoline.

Pioneered by Chevron U.S.A., Inc., a subsidiary of Chevron, and licensed to Honeywell UOP, the technology is offered to the entire industry under the ISOALKY^™ brand name.

ISOALKY^™ technology can be used in new refineries as well as in existing facilities undergoing capital expansion or retrofit applications. ISOALKY^™ technology has wider and improved feed flexibility relative to conventional alkylation technologies. Ionic liquids are regenerated on-site, eliminating the need for road or marine transportation for offsite regeneration and polymer byproduct handling.

ISOALKY^™ technology took more than 20 years of research and development and 1.9 million construction hours to complete. Chevron Salt Lake Refinery’s commissioned the world’s first commercial scale ISOALKY^™ alkylation unit in January 2021.
