FOAMING PROCESSES IN AMINE GAS PURIFICATION
Keywords:
Amine, foaming, amine system, hydrogen sulphide, carbon dioxide.Abstract
Amine solutions foam because normal froth is stabilized into foam by contaminating surfactants. Since pure amines do not form stable foams, one or more components must be present in the treating solution in order to form. Possible contaminants include not only liquid hydrocarbons and iron sulphide, but well treating fluids, amine degradation products, and other finely divided solids.
The goal of foaming control should be to minimize the level of contaminants in the amine solution. This article explains how to defoam and lists a number of causes of amine foaming.
