Abstract

Hydrogen recovery unit is important to remove H2S from the off gases generated from various units in refinery and recovers hydrogen. The recovered hydrogen reduces the quantity of hydrogen needed to be produced from hydrogen production unit required for hydro-treating processes in the refinery. The off gas generated from this unit is used as fuel gas. This is achieved at reasonable cost and with maximum protection to people, equipment, materials, and the environment. Proper operation will ensure that these goals are met. The required purity is (>99.9 mol%).
