    摘要: The simultaneous abatement of NO and SO.sub.2 in flue gas is provided by an absorption process and apparatus utilizing an absorbent composition comprising an aqueous solution of chelates and sulfite salts. Metal chelates oxidized to an inactive state are electrochemically reduced. In the electrochemical cell, nickel or stainless steel anode materials are stable and may be used in the place of platinum coated anode materials when the anolyte pH is maintained greater than 12. At these conditions, the anode is corrosion resistant with a long operating time between replacement. Ultrafiltration or Donnan dialysis may be used to separate the chelate sorbents from the waste salts to reduce the loss of expensive chelate sorbents. Alternatively, an anionic exchange membrane can be used to electrodialytically separate waste sulfur/nitrogen salts from the absorbent solution.

    摘要: An NO abatement process wherein an NO-containing fluid is contacted with a polymeric cobalt(II) dioxygen diamine complex. The aqueous solution is recovered, purified by membrane separation to remove low molecular weight reaction products, optionally electrolytically regenerated, and recycled for the NO-containing gas contact. The cobalt(II) is complexed with an amine-containing polymer such as polyethyleneimine free of acidic, e.g. carboxylate, chelating groups.
