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]
Sour gas is natural gas or any other gas containing significant amounts of hydrogen sulfide (H 2 S).. Natural gas is usually considered sour if there are more than 5.7 milligrams of H 2 S per cubic meter of natural gas, which is equivalent to approximately 4 ppm by volume under standard temperature and pressure.
[5] [6] There are physical and chemical absorption processes to removing the toxic properties of these gases, both of which involve the syngas being washed with a lean solvent in an absorber to remove the H 2 S. [7] Once the toxic gas leaves the bottom of the absorber it is sent to a regenerator where the solution is further stripped with steam ...
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.
Hydrogen sulfide (H2S) is a noxious gas characterized by its distinctive stench reminiscent of rotten eggs. [1] It goes by several colloquial names, including sewer gas, stink damp, swamp gas, and manure gas. [2] This gas naturally occurs in crude petroleum, natural gas, hot springs, and certain food items.
Binary acids or hydracids are certain molecular compounds in which hydrogen is bonded with one other nonmetallic element. [1] This distinguishes them from other types of acids with more than two constituent elements.
Sulfide (also sulphide in British English) [2] is an inorganic anion of sulfur with the chemical formula S 2− or a compound containing one or more S 2− ions. Solutions of sulfide salts are corrosive. Sulfide also refers to large families of inorganic and organic compounds, e.g. lead sulfide and dimethyl sulfide.
The deuterated form of hydrogen disulfide, deuterium disulfide D−S−S−D (dideuterodisulfane), has a similar geometry to H−S−S−H, but its tunneling time is slower, making it a convenient test case for the quantum Zeno effect, in which frequent observation of a quantum system suppresses its normal evolution.
