Hydrisom Block Flow Diagram

The Hydrisom process is a proprietary refinery pretreatment technology originally developed and licensed by Phillips Petroleum Company (Bartlesville, Oklahoma), now held by Phillips 66. It is designed as a feed-preparation unit for HF Alkylation, combining two sequential catalytic reactions in a single unit: selective hydrogenation of diolefins and olefin double-bond isomerization. The technology's name is a portmanteau of hydrogenation + isomerization, reflecting its dual function.
