Reduced Sulfur Compounds Treatment with Hydrogen Peroxide Sulfur
compounds, such as hydrogen sulfide, thiosulfates and
mercaptans, can present serious wastewater problems for
refiners. Hydrogen peroxide treatment is a cost effective way to
reduce sulfur species. Download our Refinery Sulfide Oxidation
Brochure (PDF) Hydrogen sulfide is a problem in the refining
processes and waste systems due to its offensive odor, toxicity
and potential corrosivity. Even concentrations as low as 4 parts
per billion (ppb), the odor can be detected and may be offensive
in the plant area and the surrounding communities. In addition,
hydrogen sulfide is considered toxic. Extended exposure to a few
hundred ppm can cause unconsciousness and death. Hydrogen
sulfide also supports the growth of certain filamentous
organisms such as thiothrix and beggiatoa, which are associated
with bulking problems in activated sludge treatment. This
condition can cause system upsets. Hydrogen sulfide is a
byproduct of many refining processes. Even w
