Bulk Desulfurization

Natural gas contains a wide variety of sulfur compounds, and sulfur speciation in the gas can change from pipeline to pipeline, locale to locale, and season to season. SulfaTrap™ sorbents remove all forms of organic and inorganic sulfur from hydrocarbon streams. We offer both regenerable and expendable technologies for sweetening sour gas streams with deep sulfur removal in place of, or in combination with, conventional technologies.

SulfaTrap™ sorbents effectively remove sulfides, mercaptans, tetrahydrothiophene (THT), di-sulfides and tri-sulfides, hydrogen sulfide (H2S), and carbonyl sulfide (COS). Our sorbents reduce the sulfur concentration in the gas to sub-ppmv levels to ensure maximum protection. We work closely with you to engineer the best solution for your application.
