Chevron Corporation and Honeywell have declared the commissioning and start-up of the world’s first commercial-scale ISOALKY process unit that utilizes ionic liquids to produce alkylate.
The ISOALKY technology represents a major innovation in alkylation technology.
“The ISOALKY plant is an exciting achievement for Chevron and the Salt Lake Refinery, and it’s poised to be a game-changer for the refining industry,” said Mike Coyle, president of Chevron Manufacturing. “We are proud of the talent and teamwork demonstrated by our people and Honeywell UOP to bring this project to fruition.”
“ISOALKY is a ground breaking new technology for refiners, and a lower-risk and economical solution compared to conventional liquid acid technologies that produce alkylate,” said Bryan Glover, president and CEO of Honeywell UOP. “Ionic liquids have strong acid properties that enable them to produce alkylate without the volatility of conventional acids, allowing for simpler handling procedures. Together with Chevron, Honeywell UOP has commercialized a solution that meets the rising global demand for cleaner-burning fuels at a lower cost while simplifying complex handling requirements.”
First used in Chevron’s Salt Lake City refinery, the ISOALKY technology is designed to meet the refining industry’s needs for a cost-effective alternative to conventional liquid acid systems that offer 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 by product handling.
