Low-Foaming Gas Processing Compositions And Uses Thereof

摘要

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.
