Desulfurization Sorbents. Effective utilization of natural gas, liquefied petroleum gas (LPG), and biogas (anaerobic digester gas – ADG) in fuel cell applications requires effective removal of sulfur impurities (naturally occurring sulfur compounds and sulfur bearing odorants) to prevent them from degrading the performance of the fuel cell …
SulfaTrap, Inc. has brought a new line of sorbents into the commercial area. SulfaTrapTM Sorbents are available for the removal of sulfur from various fuel streams including natural gas, LPG, biogas, biofuels, propane, logistics fuel, reformate gas and diesel fuel.
Desulfurization is the removal of sulfur or sulfur compounds (as from coal or flue gas), mostly from fuels. The most commonly required desulfurization process is in natural gas, but it is also required for flue gas, coal and oil.
Sep 06, 2018· The desulfurization and denitrogenation process reduce the impacts of sulfur and nitrogen dioxides, which can cause acid rain and environmental damage. Georgesplane Post 3 What is the reaction called that is used in hydrosesulfurization?
Sulfur content - The sulfur content, together with the allowable emission standards, determines the required SO 2 removal efficiency, the FGD system complexity and cost, and also affects sulfite oxidation.
Desulfurization Process at a capital cost of $15 MM or less for a 30,000 BPD unit and an operating cost of $0.25/bbl or less in order to be competitive as an alternative to a major revamp of moderate to
Alkylation-based desulfurization has been tested with thiophenic sulfur compounds at small scale, and it is commercially applied for light oil at large scale as the Olefinic Alkylation of Thiophenic Sulfur (OATS) process developed by …
Desulfurization efficiency of hydrotreater is decreased with an increase in boiling point of a sulfur compound and increase in the concentration of sulfur and polyaromatic compounds in the feed . In the present approach, a distillation of SRGO segregates highly refractive sulfur compounds and polyaromatics in HFGO.
