Hydrogen sulfide is a chemical compound with the formula H 2 S.It is a colorless chalcogen-hydride gas, and is poisonous, corrosive, and flammable, with trace amounts in ambient atmosphere having a characteristic foul odor of rotten eggs. [11]
Amine gas plant at a natural gas field. 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.
The instrument measures parts per billion levels of hydrogen sulfide and, to a lesser extent, methyl mercaptan, two gases which were previously shown to be associated with bad breath using gas chromatograph by Dr. Joseph Tonzetich in the late 1960s.
Mustard gas or sulfur mustard are names commonly used for the organosulfur chemical compound bis(2-chloroethyl) sulfide, which has the chemical structure S(CH 2 CH 2 Cl) 2, as well as other species. In the wider sense, compounds with the substituents −SCH 2 CH 2 X or −N(CH 2 CH 2 X) 2 are known as sulfur mustards or nitrogen mustards ...
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 from the ...
This compound is the product of the half-neutralization of hydrogen sulfide (H 2 S) with sodium hydroxide (NaOH). NaSH and sodium sulfide are used industrially, often for similar purposes. Solid NaSH is colorless. The solid has an odor of H 2 S owing to hydrolysis by atmospheric moisture.
The term "dissimilatory" is used when hydrogen sulfide (H 2 S) is produced in an anaerobic respiration process. By contrast, the term "assimilatory" would be used in relation to the biosynthesis of organosulfur compounds, even though hydrogen sulfide may be an intermediate. Dissimilatory sulfate reduction occurs in four steps: [1]
Hydrogen sulfide is also involved in the disease process of type 1 diabetes. The beta cells of the pancreas in type 1 diabetes produce an excess of the gas, leading to the death of these cells and to a reduced production of insulin by those that remain. [5] In 2005, it was shown that mice can be put into a state of suspended animation-like ...
