WebH2S is also known as Sour Gas, Swamp Gas, Sulfuretted Hydrogen, and Hydrosulfuric Acid. H2S has a familiar odor of rotten eggs at low concentrations. At high concentrations, H2S is highly toxic and often deadly. Physical Properties Boiling Point -76.60°F Freezing Point -12 l.9°F Molecular Weight 34.08 g/mole Specific Gravity 1.1895 WebHydrogen sulfide cannot normally be tolerated in Merox unit feed stocks in concentrations exceeding about 5 wt ppm [24]. This version of the Merox process utilizes gas–liquid contacting to extract low-molecular-weight mercaptans from … Hydrogen sulfide is a chemical compound with the formula H 2S. 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. The underground mine gas term for foul-smelling hydrogen sulfide … See more Hydrogen sulfide is slightly denser than air. A mixture of H 2S and air can be explosive. In general, hydrogen sulfide acts as a reducing agent, although in the presence of a base, it can act as an acid by donating a … See more Production of sulfur, thioorganic compounds, and alkali metal sulfides The main use of hydrogen sulfide is as a precursor to elemental sulfur. Several organosulfur compounds are produced using hydrogen sulfide. These include methanethiol See more Microbial: The sulfur cycle Hydrogen sulfide is a central participant in the sulfur cycle, the biogeochemical cycle of sulfur on Earth.
