The process was invented by Carl Friedrich Claus, a German chemist working in England. A British patent was issued to him in 1883. The process was later significantly modified by IG Farben. [6] Claus was born in Kassel in the German State of Hesse in 1827, and studied chemistry in Marburg before he emigrated to
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 ...
Amine gas treating, also known as amine scrubbing, gas sweetening and acid gas removal, refers to a group of processes that use aqueous solutions of various alkylamines (commonly referred to simply as amines) to remove hydrogen sulfide (H 2 S) and carbon dioxide (CO 2) from gases. [1][2][3] It is a common unit process used in refineries, and is ...
A British patent for the Claus process was issued to him in 1883. The Claus process is the most significant gas desulfurizing process, recovering elemental sulfur from gaseous hydrogen sulfide . The process was later significantly modified by German company IG Farben [1] His first wife was Mary Claus (born Brown).
The process is an alternative to the conventional Claus process that operates at 800–1,000 °C (1,470–1,830 °F). [29] A Fe catalyst combined with a Cu light absorber can produce hydrogen from ammonia (NH 3) at ambient temperature using visible light. Conventional Cu-Ru production operates at 650–1,000 °C (1,202–1,832 °F). [30]
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 ...
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]
