sulfuret

A special facility existed to extract the sulfuret of hydrogen - known as the purifier.

As such, the removal of the sulfuret of hydrogen was given the highest level of priority in the gas-works.

But these do not compare to the most hazardous contaminant in the raw coal gas: the sulfuret of hydrogen (hydrogen sulfide, HS).

Originally, purifiers were simple tanks of lime-water, also known as cream or milk of lime, where the raw gas from the retort bench was bubbled through to remove the sulfuret of hydrogen.

The sulfuretted lime was not toxic, but not greatly wanted, slightly stinking of the odor of the sulfuret, and was spread as a low grade fertilizer, being impregnated with ammonia to some degree.

Though toxic in sufficient concentrations or long exposures, the sulfuret was generally just nauseating for short exposures at moderate concentrations, and was merely a health hazard (as compared to the outright danger of "blue billy") for the gas-works employees and the neighbors of the gas-works.

Lime was sometimes still used after the iron ore had thoroughly removed the sulfuret of hydrogen, to remove carbonic acid (carbon dioxide, CO), the bisulfuret of carbon (carbon disulfide, CS), and any ammonia still aeroform after its travels through the works.
