The sulfur in the natural gas may then be burned by the end user with the formation of sulfur dioxide (SO2) typically in low ppm or even ppb levels. Once the natural gas reaches saturation any additional pressure drop and/or cooling will result in additional deposition. This can be a very big problem for cryogenic facilities such as LNG plants.

The Claus Sulfur Recovery Process — Sulfur Recovery
THE SULFUR RECOVERY UNIT (SRU) 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.
