H2S Removal

Primary oxygen carrier in the Stretford process and other desulfurization units. Facilitates the oxidation of sulfide ions to elemental sulfur, which is then recovered for industrial use

Environmental Compliance

Essential for oil refineries and biogas plants to meet stringent air quality standards by scrubbing sour gas streams

Aqueous Organic Flow Batteries

(AOFB) as the negolyte (negative electrolyte). High stability, rapid redox kinetics, and water solubility allow for high-capacity, long-cycle-life energy storage for solar and wind farms
