The new standard for sulfur removal

Increasingly stringent government regulations on sulfur emissions can be an expensive problem for many sectors, particularly the Petroleum industry. Aside from producing foul-smelling odors that harm nearby communities, high levels of sulfur emissions deteriorate overall air quality and can create acid rain. AZZURO has developed specialized solutions for cost-effective sulfur reduction, proven to remove over 99.5% of H2S, SO2, COS, CS2, and mercaptans.
