Hydrogen sulfide vapor

Hydrogen sulfide vapor reagent 86 Hydrolysis 62 ff -, acid 62... 

Vacuum process residual fuel to remove hydrogen sulfide vapors. 

AURORA YELLOW (1306-23-6) Violent reaction with strong oxidizers, iodine chloride. Contact with water, steam, or acids evolves explosive hydrogen sulfide vapors. 

In the course of the dehydration step, hydrogen sulfide also escapes. This may cause a problem, since the amount of alkali metal sulfide varies in an uncontrolled manner. In order to reach a high degree of polymerization, the alkali metal sulfide and the dichloro aromatic compound should be present in a stoichiometric ratio. Further, the hydrogen sulfide vaporized off in the dehydration step is a harmful substance. Therefore, the amount of hydrogen sulfide escaped in the dehydration step should be analyzed precisely to get the amount of sulfur still present in the reaction vessel. The hydrogen... 

Also, the emissions of uncombusted hydrogen sulfide vapors (HjS) to the atmosphere could also be (although more remotely) a potential safety issue. This happened at the Good Hope Refinery where 1 worked in 1981, when reports of noxious odors were reported from a local high school. Our plant manager appeared on the television news to assure the community that while the H S odor was bad, it was not in the least harmful to the children.
