    en.wikipedia.org/wiki/Hydrodesulfurization

    Hydrodesulfurization or hydrodesulphurisation (Commonwealth English; see spelling differences) (HDS), also called hydrotreatment or hydrotreating, is a catalytic chemical process widely used to remove sulfur (S) from natural gas and from refined petroleum products, such as gasoline or petrol, jet fuel, kerosene, diesel fuel, and fuel oils.

    en.wikipedia.org/wiki/Flue-gas_desulfurization

    Flue-gas desulfurization (FGD) is a set of technologies used to remove sulfur dioxide (SO 2) from exhaust flue gases of fossil-fuel power plants, and from the emissions of other sulfur oxide emitting processes such as waste incineration, petroleum refineries, cement and lime kilns.

  4. Desulfurization - Wikipedia

    en.wikipedia.org/wiki/Desulfurization

    Desulfurization or desulphurisation is a chemical process for the removal of sulfur from a material. This involves either the removal of sulfur from a molecule (e.g. A=S → A:) or the removal of sulfur compounds from a mixture such as oil refinery streams. [1] Example of desulfurization of thioacetals using Raney nickel

  5. Wet sulfuric acid process - Wikipedia

    en.wikipedia.org/wiki/Wet_sulfuric_acid_process

    The WSA process can be applied in all industries where sulfur removal presents an issue. The wet catalysis process is used for processing sulfur-containing streams, such as: [1] H 2 S gas from e.g. amine gas treating unit; Off-gas from sour water stripper (SWS) gas; Off-gas from Rectisol; Spent acid from an alkylation unit; Claus process tail gas

  6. SNOX process - Wikipedia

    en.wikipedia.org/wiki/SNOX_process

    In several places there is a need for both electric power and sulfuric acid. A cheap high-sulfur fuel such as petroleum coke can be used for power generation, while the flue gas is cleaned in an SNOX plant producing sulfuric acid. Elemental sulfur is fired in the SNOX plant in order to produce the desired amount of sulfuric acid.

  8. Sulfation - Wikipedia

    en.wikipedia.org/wiki/Sulfation

    Sulfation is a process used to remove "sulfur" from the combustion of fossil fuels. The goal is to minimize the pollution by the combusted gases. Combustion of sulfur-containing fuels releases sulfur dioxide , which, in the atmosphere, oxidizes to the equivalent of sulfuric acid , which is corrosive.
