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.

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.

5. Shell–Paques process - Wikipedia

   en.wikipedia.org/wiki/Shell–Paques_process

   In many situations the process can be used for sulfur removal and recovery. When sulfur recovery is desired, the elemental sulfur produced in the aerobic bioreactor will be separated from the aqueous effluent in a separator inside of the reactor. The excess sulfur will be removed as aqueous slurry or cake of up to 65% dry solids content.

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.

7. Fluid catalytic cracking - Wikipedia

   en.wikipedia.org/wiki/Fluid_catalytic_cracking

   After further processing for removal of sulfur compounds, the cracked naphtha becomes a high-octane component of the refinery's blended gasolines. The main fractionator offgas is sent to what is called a gas recovery unit where it is separated into butanes and butylenes , propane and propylene , and lower molecular weight gases ( hydrogen ...
