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. [1] The term usually refers to the removal of sulfur from a molecule or a material by hydrogenolysis: [2] R 2 S + 2 H 2 → 2RH + H 2 S. Hydrogen is the ultimate sulfur acceptor. As applied to oil refinery streams, the conversion is known as ...
A typical fluid catalytic cracking unit in a petroleum refinery. Fluid catalytic cracking (FCC) is the conversion process used in petroleum refineries to convert the high-boiling point, high-molecular weight hydrocarbon fractions of petroleum (crude oils) into gasoline, alkene gases, and other petroleum products.
Ever since the late 1950s, when commercial quantities of oil were first discovered in Nigeria's Niger Delta basin, West Africa has been an area of interest for oil and gas exploration and ...
A new, emerging flue gas desulfurization technology has been described by the IAEA. [16] It is a radiation technology where an intense beam of electrons is fired into the flue gas at the same time as ammonia is added to the gas. The Chendu power plant in China started up such a flue gas desulfurization unit on a 100 MW scale in 1998.
Energy in Africa is a scarcer commodity than in the developed world – annual consumption is 518 KWh in Sub-Saharan Africa, the same amount of electricity used by an individual in an Organization for Economic Cooperation and Development (OECD – example is the U.S.) country in 25 days. [12] More than 500 million people live without electricity.
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 ...
