  • Low-foaming gas processing compositions and uses thereof
    Patent number: 7879918
    Abstract: The invention relates to low-foaming gas processing compositions comprising (a) a silicone antifoam component comprising a base silicone fluid and a particulate metal oxide; (b) an emulsifying component in an amount suitable for the at least substantial emulsification of the silicone antifoam component in water; (c) a polypropylene glycol component at least partially soluble, emulsifiable, and/or dispersible in water; (d) a water-soluble or water-dispersible gas processing agent; and (e) water. The invention also relates to methods for processing a gas by treating the gas with these foam suppressing compositions.

  • Silicone antifoam composition and method using same
    Publication number: 20080121104
    Abstract: There is provided herein a composition which comprises a silicone copolymer and/or terpolymer component containing a polyether moeity (a); and, a water-soluble and/or water dispersible gas-processing component (b); said composition being substantially free of metal oxide-filled non-polyether moiety-containing silicone fluid. There is also provided herein a method for processing a gas comprising treating the gas with said composition.
