Chevron starts up new salt-based alkylation unit from Honeywell

April 14/2021

MOSCOW (MRC) -- Chevron Corporation and Honeywell announced 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, said the company.

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 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.

Through a partnership with Honeywell UOP, the ISOALKY process unit at Chevron’s refinery in Salt Lake City will be able to meet the growing demand for higher-octane blending components that lower the environmental impact of gasoline.

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. More information about ISOALKY™ technology can be found here.

As MRC informed earlier, Chevron Phillips Chemical (CP Chem) halted production at its cracker in Sweeny (Old Ocean, TX, USA) on February 15 due to cold weather. Extreme cold and instability of power supply and fuel gas supply systems led to shutdowns of existing cracking units No. 22, 24 and 33 and the production of polyethylene (PE). The company's total ethylene production capacity in Sweeney is 1.975 million tonnes per year of ethylene, 165 thousand tonnes of propylene, 500 thousand tonnes of HDPE and 500 thousand tonnes of LDL.

Ethylene and propylene are feedstocks for producing polyethylene (PE) and polypropylene (PP).

According to MRC's ScanPlast report, Russia's estimated PE consumption totalled 241,030 tonnes in January 2021 versus 217,890 tonnes a year earlier. Only shipments of low density polyethylene (LDPE) and high density polyethylene (HDPE) increased. At the same time, PP shipments to the Russian market reached 141,870 tonnes in January 2021 versus 123,520 tonnes a year earlier. Supply of homopolymer PP and PP block copolymers increased.

Honeywell UOP is a leading international supplier and licensor of process technology, catalysts, adsorbents, equipment, and consulting services to the petroleum refining, petrochemical, and gas processing industries. Honeywell UOP is part of Honeywell’s Performance Materials and Technologies strategic business group, which also includes Honeywell Process Solutions, a pioneer in automation control, instrumentation and services for the oil and gas, refining, petrochemical, chemical and other industries.
