An Effective Solution for Elemental Sulfur Deposition in

2015-12-10 · 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.
