2. Hydrodesulfurization - Wikipedia

   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.

3. Flue-gas desulfurization - Wikipedia

   en.wikipedia.org/wiki/Flue-gas_desulfurization

   An alternative to removing sulfur from the flue gases after burning is to remove the sulfur from the fuel before or during combustion. Hydrodesulfurization of fuel has been used for treating fuel oils before use. Fluidized bed combustion adds lime to the fuel during combustion. The lime reacts with the SO 2 to form sulfates which become part of ...

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. Amine gas treating - Wikipedia

   en.wikipedia.org/wiki/Amine_gas_treating

   In fact, the vast majority of the 64,000,000 metric tons of sulfur produced worldwide in 2005 was byproduct sulfur from refineries and other hydrocarbon processing plants. [7] [8] Another sulfur-removing process is the WSA process which recovers sulfur in any form as concentrated sulfuric acid. In some plants, more than one amine absorber unit ...

6. 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

7. Fuel polishing - Wikipedia

   en.wikipedia.org/wiki/Fuel_polishing

   Fuel polishing is the technical cleaning process used to remove or filter microbial contamination from oil and hydrocarbon fuel in storage. It is essentially the removal of water, sediment and microbial contamination from such fuels as diesel, red diesel and biodiesel. This fuel contamination, also known as 'fuel bugs', or 'diesel bugs', or 'so ...
