The Claus process is the most significant gas desulfurizing process, recovering elemental sulfur from gaseous hydrogen sulfide. First patented in 1883 by the chemist Carl Friedrich Claus, the Claus process has become the industry standard. The multi-step Claus process recovers sulfur from the gaseous hydrogen sulfide found in raw natural gas ...
An integrated gasification combined cycle (IGCC) is a technology using a high pressure gasifier to turn coal and other carbon based fuels into pressurized gas—synthesis gas (syngas). It can then remove impurities from the syngas prior to the electricity generation cycle. Some of these pollutants, such as sulfur, can be turned into re-usable ...
CrystaSulf. CrystaSulf is the trade name for a chemical process used for removing hydrogen sulfide (H 2 S) from natural gas, synthesis gas and other gas streams in refineries and chemical plants. [1] [2] CrystaSulf uses a modified liquid-phase Claus reaction to convert the hydrogen sulfide (H 2 S) into elemental sulfur which is then removed ...
Hydrodesulfurization (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. [1][2][3] The purpose of removing the sulfur, and creating products such as ...
Carl Friedrich Claus (9 November 1827 – 29 August 1900) was a German chemist and inventor. He patented the Claus process. Life. Claus was born in Kassel. He studied chemistry at University of Marburg in Germany. He emigrated to England, where he worked as chemist. A British patent for the Claus process was issued to him in
Clausius–Clapeyron relation. The Clausius–Clapeyron relation, in chemical thermodynamics, specifies the temperature dependence of pressure, most importantly vapor pressure, at a discontinuous phase transition between two phases of matter of a single constituent. It is named after Rudolf Clausius [1] and Benoît Paul Émile Clapeyron. [2]
1894. The Frasch process is a method to extract sulfur from underground deposits by taking advantage of the low melting point of sulfur. It is the only industrial method of recovering sulfur from elemental deposits. [1] Most of the world's sulfur was obtained this way until the late 20th century, when sulfur recovered from petroleum and gas ...
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. These processes are of ...
