  2. Hydrogen sulfide - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_sulfide

    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]

  3. Sour gas - Wikipedia

    en.wikipedia.org/wiki/Sour_gas

    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.

  4. Acid gas - Wikipedia

    en.wikipedia.org/wiki/Acid_gas

    [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 ...

  5. Amine gas treating - Wikipedia

    en.wikipedia.org/wiki/Amine_gas_treating

    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.

  6. Hydrogen sulfide sensor - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_sulfide_sensor

    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.

  7. Binary acid - Wikipedia

    en.wikipedia.org/wiki/Binary_acid

    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.

  8. Sulfide - Wikipedia

    en.wikipedia.org/wiki/Sulfide

    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.

  9. Hydrogen disulfide - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_disulfide

    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.
