Hydrogen Sulfide is dangerous to the environment, colorless, very poisonous, highly flammable gas with the characteristic foul odor of rotten eggs. Heavier than air, it tends to accumulate at the bottom of poorly ventilated spaces.
Although very pungent at first, it quickly deadens the sense of smell, so potential workers may be unaware of its presence until it is too late. 800 ppmv is the lethal concentration for 50% of humans for 5 minutes exposure.H2S removal system is the best way to clean the environment.
This Hydrogen Sulfide gas is a common off-gas that is produced in the Steel and Mining industry. At even very low concentration levels H2S is considered a fatal gas. H2S is commonly reduced by thermal oxidation to SO2 and SO3 for possible usage in other plant processes or if not utilized for other applications may be removed by the use of a wet scrubber.
Many industrial engineers and H2S application specialist have been involved with oxidizer systems which have been used in the treatment of H2S and CS2 pollutants.
Many, after being involved in many failed or sub-standard trials have devoted the time in research and product development to design and manufacture regenerative thermal oxidizers that works. RTO’s is utilized to improve fuel efficiencies and to reduce NOX production that would come from a standard Direct-Fired ems.
