Sulfur handling - Shell sulfur degassing process

Applications: The Shell Sulfur Degassing Process has been developed to remove H2S and H2Sx from liquid sulfur eliminating potential toxic and explosion hazards associated with handling, transport and storage of liquid sulfur. Elemental sulfur produced by the Claus process contains both physically dissolved H2S and chemically bound H2S in the form of hydrogen polysulfides (sulfanes): H2Sx.

Example - sulfur from refineries - Consequential LCA

Sulfur is a by-product of processing natural gas and refining high-sulfur crude oils. According to US EPA most of the 68,000,000 metric tons of sulfur produced worldwide in 2012 was a by-product from refineries and other hydrocarbon processing plants (US EPA 2014). ... Example –sulfur from refineries.

Sulfite process - Wikipedia

The sulfite process produces wood pulp which is almost pure cellulose fibers by using various salts of sulfurous acid to extract the lignin from wood chips in large pressure vessels called digesters. The salts used in the pulping process are either sulfites (SO 3 2−), or bisulfites (HSO 3 −), depending on the pH.

Pollution Prevention in the Pulp and Paper Industries

The major air emissions of the industry come from sulfite mills as recovery gurnaces and burnes, sulfur oxides (SOx), from Kraft operation as reduced sulfur gases and odor problems, from wood-chips digestion, spent liquor evaporation and bleaching as volatile organic carbons (VOCs), and from combustion process as nitrogen oxidies (NOx) and SOx.
