world’s first commercial ISOALKY™ ionic liquids alkylation unit

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.

how was ISOALKY™ developed?

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.
