ABSTRACT OF THE DISCLOSURE A process is disclosed for inhibiting or eliminating foams and bubbles produced in the course of treating acidic gases with an aqueous amine solution. Defoaming is effected by the use of a modified silicone compound having the general formula Image where R1 - R8 are organic residues of 1 - 10 carbons, and n is an integer, and characterized by part of R1 - R8 being substituted by a group of the general formula - R9 - OH - where R9 is a hydrocarbon or organic residue of 1 - 10 carbons; or characterized by part of R1 - R8 being substituted by a group of the general formula - NR10OR11 where R10.and R11 are either hydrogen or hydrocarbon or organic residue of 1 - 10 carbons.
