A New Era for Alkylation: Ionic Liquid Alkylation -- ISOALKY™ Process Technology
10 October 2019
Sponsor: Honeywell UOP
Chevron and Honeywell UOP have developed a commercially viable next-generation alkylate gasoline manufacturing process, ISOALKY Technology, which has performance benefits (yield, product octane number, safety and environmental) over the conventional acid-based processes. The ISOALKY Catalyst is a non-volatile ionic liquid that operates efficiently via on-line regeneration with the added benefits of no acid soluble oil (ASO) disposal and no solid by-product formation.
ISOALKY technology can be used for green field plants or retrofit/expansion of existing alkylation units and the capital and operating costs are comparable to or better than other commercially available alkylation processes. The Technology is being commercialized in two refineries: one for retrofitting of a Chevron HF alkylation plant and the other for a grass-root alkylation plant. Construction for the Chevron conversion project began in 2018, with the ISOALKY plant due for startup in late 2020. Start-up of the second commercial plant is expected in 2021.
In this presentation, we introduce how ISOALKY Technology provides greater flexibility in feedstocks, smaller volume of catalyst required, optimized operating conditions to increase octane and to allow use of lower metallurgy such as carbon steel, and decreased risk in transportation and handling of the solution.
