Patent ID: 7879918

Claim:
A low-foaming gas processing composition consisting essentially of: (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 wherein the silicone antifoam component further comprises (i) one or more branched silicone resins selected from the group consisting of MQ, MDQ and T silicone resins, or (ii) one or more catalysts capable of promoting condensation reactions between siloxy groups; wherein M represents monovalent groups of formula (CH 3 ) 3 SiO 1/2 , D represents divalent groups of formula (CH 3 ) 2 SiO 2/2 , T represents trivalent groups of formula (CH 3 )SiO 3/2 , and Q represents tetravalent groups of formula SiO 4/2 .
