Remove Organic Sulfur Species like Mercaptans and COS
SulfaTrap™ sorbents can complement the solvent scrubbers, offering an economic solution to bring the sulfur concentration to very low concentrations (< 0.1 ppmv total sulfur).
In sour gas sweetening applications, amine units are traditionally used for removing the bulk of the sulfur. However, most commercial solvents cannot effectively remove the organic sulfur species such as mercaptans and COS. These secondary compounds can cause the treated gas to exceed pipeline sulfur specifications.
SulfaTrap™-R5 sorbent is regenerated by applying a mild temperature swing using a clean sweep gas stream. This concentrated mixture of sulfur-laden sweep gas is further treated to provide a permanent sink for the sulfur compounds. For the tail gas treatment, SulfaTrap offers a combination of thermal oxidizer and sulfur dioxide (SO2) scrubber to provide a permanent sink for organic sulfur (organic Sulfur may be converted to SO2 which is then mineralized using a dry-solid or wet scrubbing system).
