The Claus Sulfur Recovery Process — Sulfur Recovery

The Sulfur Recovery Unit (SRU) is based on the modified Claus Process, which is a two-step reaction scheme overall. A portion of the total H2S is burned in the Reaction Furnace to form SO2. Then, the H2S and SO2 react, at an optimal 2:1 ratio, to form elemental Sulfur (Sx) across the Claus Reactors. After each catalytic stage, liquid sulfur is

Sulfur recovery is an important industrial process for fossil fuel clean consumption, in which H2S is firstly separated from the gas stream from the hydrodesulfurization process or gasified gas of coal or biomass. Meanwhile, almost equivalent half amount of SO2 is produced from the boiler on-site due to the power and steam generation or the fluid catalytic cracking process in a refinery.
