Abstract: The protective effect of amines on steel corrosion under simulated conditions of gas condensate fields are studied. It is shown that primary amines are less effective than secondary and tertiary ones in terms of steel protection, especially in vapor phase. The authors also studied the impact of C_H2S, pH, temperature and presence of a hydrocarbon phase on protective effect of chemical compounds considered.
