    Abstract: For the selective removal of sulfur from gases, a physical scrubbing agent is used, comprising a heterocycle having five or more ring atoms, which contains two heteroatoms, one of which is nitrogen and the other of which is oxygen or nitrogen; and the heteroatoms in the rings of even member number of atoms occupy; one of the positions from 1,2 to 1,n/2 and, in the rings of uneven member number of atoms occupy one of the positions from 1,2 up to 1, (n-1)/2. Further, the nitrogen heteroatom(s) present in the ring is/are either double bonded or single bonded but, if single bonded, the nitrogen is organo-substituted.

    Abstract: Sulfur dioxide is removed from a fluid containing SO.sub.2 by employing as an absorbent therefor an aqueous solution of compound represented by Formula I: ##STR1## wherein X is --O--, --NR.sup.1 --, or --N.dbd.; each Y is independently --(CR.sup.2.sub.2)--, --(C.dbd.O)--, --O--, --NR.sup.1 --, --N.dbd., or --C(R.sup.2).dbd.; each R.sup.1 or R.sup.2 is independently hydrogen; an alkyl group; a hydroxyalkyl group; an aldehyde group; a carboxylic acid or salt group; or an alkyl group containing an aldehyde group, a carboxylic acid or salt group, ketone, carboxylic ester, ether, or sulfoxide group; and m is an integer preferably of from 2 to about 4. The absorbent solution preferably can be thermally regenerated by heating to remove SO.sub.2.

    Abstract: The present invention relates to a cyclic continuous process and composition for the removal of NO and SO.sub.2 from a variety of fluid streams. A fluid stream containing NO and SO.sub.2 is contacted with an aqueous solution of water-soluble organic polymeric chelate containing a polyvalent metal, e.g., Fe (II). The NO is catalytically absorbed and in the presence of SO.sub.2, the imidodisulfonate is formed. Optionally, a reducing agent, such as sodium hydrogen sulfide, is added to maintain the polyvalent metal in the reduced state. The process next includes removal of the imidodisulfonate formed. The separation of water and low molecular weight materials and products, e.g. molecular weight below 500, usually occurs by ultrafiltration or dialysis, with recycle and re-use of the polyvalent metal chelate.
