ABSTRACT:
A method for inhibiting foam formation in a stripper of an amine unit is disclosed. The addition of non-foaming demulsifiers to the liquid, compressed hydrocarbon stream entering or the aqueous organic amine stream entering or exiting an absorber of an amine unit effectively inhibits foam formation in the amine unit stripper. Foam formation in the stripper is inhibited by controlling the entrainment of hydrocarbon in the alkaline amine stream entering the stripper through demulsification treatment in the absorber.
