The increased foaming of diethanolamine solution during the absorption purification of natural gas from acidic components is a whole complex of problems caused by the impurities of different origin in amine solution. The paper focuses on the experimental results of studying the influence of the following impurities on the foaming of the amine solution: corrosion inhibitor, hydrocarbons (diesel fraction), mechanical impurities, decomposition products of diethanolamine in concentrations from the average to the maximum observed in the operation of natural gas desulphurization plants. There has been observed effectiveness of Siloktrim antifoam in respect of amine solution contaminated with various impurities. It has been stated that the greatest foaming caused the presence of decomposition products of diethanolamine, and the smallest - decomposition products of diesel fraction and corrosion inhibitor. The effectiveness of the defoamer is most evident in relation to reducing the height of the foam and not so much evident in relation to stability of the foam. In the case of a solution of diethanolamine contaminated with an inhibitor, the defoamer adversely affects the stability of the foam.
