Hydrogen sulfide gas is a dangerous mixture that needs to be addressed wherever it is present, which includes many industrial applications. H2S is a strong neurotoxin and has dangerous stimulating effects on mucous membranes when humans become exposed. The gas is also a highly flammable environmental hazard. For these reasons, we developed the H2S scrubber which acts as exhaust purification equipment and effectively neutralizes the gas so as to prevent any dangerous exposure to humans and the environment.
