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. Petroleum refining processes - Wikipedia

   en.wikipedia.org/wiki/Petroleum_refining_processes

   Petroleum refinery in Anacortes, Washington, United States. Petroleum refining processes are the chemical engineering processes and other facilities used in petroleum refineries (also referred to as oil refineries) to transform crude oil into useful products such as liquefied petroleum gas (LPG), gasoline or petrol, kerosene, jet fuel, diesel oil and fuel oils.

4. Amine gas treating - Wikipedia

   en.wikipedia.org/wiki/Amine_gas_treating

   In oil refineries, that stripped gas is mostly H 2 S, much of which often comes from a sulfur-removing process called hydrodesulfurization. This H 2 S-rich stripped gas stream is then usually routed into a Claus process to convert it into elemental sulfur. In fact, the vast majority of the 64,000,000 metric tons of sulfur produced worldwide in ...

5. Syngas to gasoline plus - Wikipedia

   en.wikipedia.org/wiki/Syngas_to_gasoline_plus

   The main product of the Fischer–Tropsch process, synthetic crude oil, requires additional refining to produce fuel products such as diesel fuel or gasoline. This refining typically adds additional costs, causing some industry leaders to label the economics of commercial-scale Fischer–Tropsch processes as challenging. [9]

6. Fluid catalytic cracking - Wikipedia

   en.wikipedia.org/wiki/Fluid_catalytic_cracking

   The feedstock to the FCC conversion process usually is heavy gas oil (HGO), which is that portion of the petroleum (crude oil) that has an initial boiling-point temperature of 340 °C (644 °F) or higher, at atmospheric pressure, and that has an average molecular weight that ranges from about 200 to 600 or higher; heavy gas oil also is known as ...

7. Atmospheric distillation of crude oil - Wikipedia

   en.wikipedia.org/wiki/Atmospheric_distillation...

   The hot crude oil is then passed into a distillation column that allows the separation of the crude oil into different fractions depending on the difference in volatility. The pressure at the top is maintained at 1.2–1.5 atm [ 2 ] so that the distillation can be carried out at close to atmospheric pressure, and therefore it is known as the ...
