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 ...
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 ...
The bisulfide anion is subsequently regenerated by heating of the amine sulfide solution. Hydrogen sulfide generated in this process is typically converted to elemental sulfur using the Claus Process.

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 ...
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 ...
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.
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 ...
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 ...
