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.
In this sense, the European Union has taken steps to decrease the sulfur content in diesel below 10 ppm, [6] while the US has made efforts to restrict the sulfur content in diesel and gasoline to a maximum of 15 ppm. [7] The reduction of sulfur compounds in oil fuels can be achieved by a process named desulfurization. [8]
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
Today, refineries are struggling to find ways to dispose of their increasing amount of sulfurous streams and waste products. Large amounts of high-sulfur residuals, particularly heavy oil and petroleum coke, are being produced and sold as fuel to the marine market or the cement industry.
The Dangote Refinery is an oil refinery owned by Dangote Group that was inaugurated on 22 May 2023 [1] in Lekki, Nigeria.When fully operational, it is expected to have the capacity to process about 650,000 barrels of crude oil per day, making it the largest single-train refinery in the world.
The Shell–Paques process, also known by the trade name of Thiopaq O&G, [1] is a gas desulfurization technology for the removal of hydrogen sulfide from natural-, refinery-, synthesis- and biogas. The process was initially named after the Shell Oil and Paques purification companies. After accession of a dedicated joint venture by the founders ...
KPRL was founded in 1960. It was originally founded by Shell and BP to distribute and supply the East Africa with oil products. Kenya Petroleum Refineries Limited was established as East African Oil Refineries Limited. The first refinery building with distillation, hydro-treating, catalytic reforming and bitumen production units was ...
Hydrogen sulfide produced, for example, in the hydro-desulfurization of refinery naphthas and other petroleum oils, is converted to sulfur in Claus plants. [2] The reaction proceeds in two steps: 2 H 2 S + 3 O 2 → 2 SO 2 + 2 H 2 O 4 H 2 S + 2 SO 2 → 3 S 2 + 4 H 2 O
