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 ]
Sodium hydrosulfide is the chemical compound with the formula NaSH. 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.
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 is produced in small amounts by some cells of the mammalian body and has a number of biological signaling functions. Only two other such gases are currently known: nitric oxide (NO) and carbon monoxide (CO).
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.
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.
[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 ...
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.
