	Hydrogen sulfide - Wikipedia, the free encyclopedia (Site not responding. Last check: 2007-10-10)
		Hydrogren sulfide producing bacteria also operate in the human colon, and the odor of flatulence is largely due to trace amounts of the gas.
		Hydrogen sulfide can also result from industrial activities, such as food processing, sewage treatment, coke ovens, paper mills (using the sulphate method), tanneries, and petroleum refineries, in coal mines (as iron sulfides such as pyrite decompose) and anywhere where sulfur comes in contact with organic material at high temperatures.
		Hydrogen sulfide is a major participant in the sulfur cycle, the biogeochemical cycle of sulfur on Earth.

		The US developed the Girdler Sulfide chemical exchange production process which was first demonstrated on a large scale at the Dana, Indiana plant in 1945 and at the Savannah River Plant, South Carolina in 1952.
		It used the Girdler sulfide process to produce heavy water, and required 340,000 tonnes of feed water to produce one tonne of heavy water.
		Also, the Girdler process involves large amounts of hydrogen sulfide, raising environmental concerns if there should be a release.

	Girdler sulfide process - Wikipedia, the free encyclopedia
		The Girdler sulfide process is an industrial production method for making heavy water (deuterium oxide), an important component of many nuclear reactors because it acts as a neutron moderator.
		Demineralised and deaerated water is fed to the cold tower where deuterium migration preferentially takes place from the hydrogen sulfide gas to the liquid water.
		This "enriched" water from the cold tower is fed to the hot tower where deuterium transfer takes place from the liquid water to the hydrogen sulfide gas.

		Isotope separation is the process of concentrating specific isotopes of a chemical element by removing other isotopes.
		chemical processes, isotopes of the same element have nearly identical chemical properties, which makes this type of separation impractical, except for separation of deuterium.
		Isotope separation is an important process for both peaceful and military nuclear technology, and therefore the capability that a nation has for isotope separation is of extreme interest to the intelligence community.

	Method for heavy-water extraction from non-electrolytic hydrogen streams using a combined electrolysis and catalytic ...
		For either a kinetic process or an equilibrium process, the deuterium to protium isotope separation factor,.alpha., is rigorously defined as the deuterium to protium atom ratio in the liquid phase, divided by the deuterium to protium atom ratio in the gas phase.
		Expressed symbolically, this separation factor,.alpha., is written as: ##EQU1## where X=atom fraction of deuterium in the liquid phase (water) with respect to total hydrogen (mass 1 and 2) in that phase, and y=atom fraction of deuterium in the gas phase (hydrogen gas) with respect to total hydrogen (mass 1 and 2) in that phase.
		In the process essentially all the liquid water feed is electrolysed to give hydrogen and it is necessary to establish a criterion for the relative flow of non-electrolytic hydrogen to electrolytic hydrogen in the catalyst column.

	Industrial process Summary
		Most fugitive emissions are caused by activities involving the production of dust, such as soil erosion and strip mining,or building demolition, or the use of volatile compounds.
		In a steel-making complex, for example, there are several identifiable smokestacks from which emissions come, but there are also numerous sources of fugitive emissions, which escape into the air as a result of processes such as producing coke, for which there is no identifiable smokestack.
		The control of fugitive emissions is generally much more complicated and costly than the control of smokestack emissions for which known add-on technologies to the smokestack have been developed.
