First Ever Commercial Scale Alkylation Unit Starts Up in Utah

4/13/2021

Honeywell announced on the 13^th of April that that the commissioning and start-up procedures for the ISOALKY process unit at Chevron’s Salt Lake City refinery have been completed. This process unit is the first of its kind in the world on a commercial scale and is being touted as a major innovation in this type of technology.

Honeywell’s ISOALKY technology is designed to use ionic liquids instead of the more common hydrofluoric and/or sulfuric acids as the catalyst to produce high-octane blending components to lessen the current environmental impacts of gasoline. Honeywell President and CEO Bryan Glover stated that “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.”

This unit involved a retrofit of and existing unit and will increase operating efficiency and feedstock flexibility, along with an unspecified capacity increase. The success of this revamp is expected to lead to additional units in North America and in China as well.
