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]
Piles of sulfur produced in Alberta by the Claus process awaiting shipment at docks in Vancouver, Canada. The Claus process is the most significant gas desulfurizing process, recovering elemental sulfur from gaseous hydrogen sulfide. First patented in 1883 by the chemist Carl Friedrich Claus, the Claus process has become the industry standard.
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.
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.
Mining accidents can occur from a variety of causes, including leaks of poisonous gases such as hydrogen sulfide [2] or explosive natural gases, especially firedamp or methane, [3] dust explosions, collapsing of mine stopes, mining-induced seismicity, flooding, or general mechanical errors from improperly used or malfunctioning mining equipment (such as safety lamps or electrical equipment).
A hiker was found alive this week in the remote wilderness of northwestern Canada, where he had been lost for more than five weeks, authorities said.
A hiker has miraculously been found alive more than a month after he vanished in the Canadian wilderness. Sam Benastick, 20, had set off on a 10-day camping trip to Redfern-Keily Park in the ...
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).
