  2. Claus process - Wikipedia

    en.wikipedia.org/wiki/Claus_process

    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 ...

  3. Amine gas treating - Wikipedia

    en.wikipedia.org/wiki/Amine_gas_treating

    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 ...

  4. Clausius–Clapeyron relation - Wikipedia

    en.wikipedia.org/wiki/Clausius–Clapeyron_relation

    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]

  5. Integrated gasification combined cycle - Wikipedia

    en.wikipedia.org/wiki/Integrated_gasification...

    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 ...

  6. Liquefaction of gases - Wikipedia

    en.wikipedia.org/wiki/Liquefaction_of_gases

    Liquefaction of gases. Liquefaction of gases is physical conversion of a gas into a liquid state (condensation). The liquefaction of gases is a complicated process that uses various compressions and expansions to achieve high pressures and very low temperatures, using, for example, turboexpanders.

  7. Carl Friedrich Claus - Wikipedia

    en.wikipedia.org/wiki/Carl_Friedrich_Claus

    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 1883. The Claus process is the most significant gas desulfurizing process, recovering elemental sulfur from gaseous hydrogen sulfide.

  8. Frasch process - Wikipedia

    en.wikipedia.org/wiki/Frasch_process

    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 ...

  9. Hydrodesulfurization - Wikipedia

    en.wikipedia.org/wiki/Hydrodesulfurization

    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 ...
