VPSA as a Reactant & Debottleneck Gas

  Oxygen is used directly as a process gas as a reactant or indirectly to enrich the oxygen level of other streams for the purpose of debottlenecking, reducing emissions and expanding operating flexibility. Oxidation processes include ethylene oxide, titanium dioxide, propylene oxide, vinyl chloride monomer and vinyl acetate. Refinery uses include sulpher recovery, catalyst regeneration, waste destruction and catalytic cracking regenerator capacity increase.
