sulfuret การใช้

• 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.
• 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.
• Lime was sometimes still used after the iron ore had thoroughly removed the sulfuret of hydrogen, to remove carbonic acid ( carbon dioxide, CO 2 ), the bisulfuret of carbon ( carbon disulfide, CS 2 ), and any ammonia still aeroform after its travels through the works.
• 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.
