Hydrogen Sulfide, H2S Specialty Gas

Hydrogen Sulfide, H2S Specialty Gas
Product Description
Hydrogen sulfide is an inorganic compound that is a flammable acid gas at
standard conditions and has a rotten egg smell in low concentrations.
Hydrogen sulfide is a colorless, highly toxic, flammable gas with a stench
characteristic of rotten eggs. It is usually caused by bacterial breakdown of
organic matter in the absence of oxygen, such as in swamps and sewers where
anaerobic digestion can take place. It is also present in volcanic gases,
"natural gas" and some well waters. Hydrogen sulfide has many names, some of
which are ancient.
Crude oil contains small amounts of hydrogen sulfide, but natural gas can
contain up to 90 percent hydrogen sulfide. About 10% of total global H2S
emissions are caused by human activities.
