    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 emulsifÊcation 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.

    Abstract: The invention relates to a method for separating emulsions of oil and water, the method comprising incorporating a demulsifying-effective amount of a silicone demulsifier into an emulsion comprising an oil phase and an aqueous phase, the silicone demulsifier having a molecular structure comprising a polysiloxane backbone of at least two siloxane units covalently bound to (i) one or more alkylene oxide groups comprising one or more alkylene oxide units independently having one to five carbon atoms, and (ii) one or more oxirane-containing and/or oxetane-containing groups, wherein said oxirane or oxetane is optionally ring-opened by reaction with a chemical or group capable of ring-opening an oxirane or oxetane ring, respectively, and wherein a solid filler is substantially excluded from the silicone demulsifier and emulsion. The invention also relates to compositions containing the above-described demulsifier and the water and oil phases of an emulsion.
