  2. Hydrogen sulfide - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_sulfide

    Many metal and nonmetal sulfides, e.g. aluminium sulfide, phosphorus pentasulfide, silicon disulfide liberate hydrogen sulfide upon exposure to water: [28] 6 H 2 O + Al 2 S 3 → 3 H 2 S + 2 Al(OH) 3. This gas is also produced by heating sulfur with solid organic compounds and by reducing sulfurated organic compounds with hydrogen.

  3. Biogenic sulfide corrosion - Wikipedia

    en.wikipedia.org/wiki/Biogenic_sulfide_corrosion

    Corrosion may occur where stale sewage generates hydrogen sulfide gas into an atmosphere containing oxygen gas and high relative humidity. There must be an underlying anaerobic aquatic habitat containing sulfates and an overlying aerobic aquatic habitat separated by a gas phase containing both oxygen and hydrogen sulfide at concentrations in excess of 2 ppm.

  4. Sewer gas - Wikipedia

    en.wikipedia.org/wiki/Sewer_gas

    Sewer gas is a complex, generally obnoxious smelling mixture of toxic and nontoxic gases produced and collected in sewage systems by the decomposition of organic household or industrial wastes, typical components of sewage. [1] Sewer gases may include hydrogen sulfide, ammonia, methane, esters, carbon monoxide, sulfur dioxide and nitrogen oxides.

  5. Sulfur water - Wikipedia

    en.wikipedia.org/wiki/Sulfur_water

    This may be due to the use of well water, poorly treated city water, or water heater contamination. Various methods exist to treat sulfur in water. These methods include Filtration of the water using a carbon filter (useful for very small amounts of hydrogen sulfide) Filtration of the water through a canister of manganese oxide coated greensand

  6. Sour gas - Wikipedia

    en.wikipedia.org/wiki/Sour_gas

    In addition to being toxic, hydrogen sulfide in the presence of water also damages piping and other equipment handling sour gas by sulfide stress cracking. Natural gas typically contains several ppm of volatile sulfur compounds, but gas from one well in Canada is known to contain 90% hydrogen sulfide and others may have H 2 S contents in the ...

  7. 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.
