USE OF AN ABSORBENT SOLUTION IN A GAS DEACIDIFICATION PROCESS TO LIMIT CORROSION OF LOW-ALLOY STEEL EQUIPMENT

摘要

The present invention relates to the use of an absorbent solution in a deacidizing method of a gaseous effluent containing the acid compounds such as co2 or the h2s in order to limit the corrosion of equipment manufactured in low-alloy steel and to absorb the acid compounds of the gaseous effluent by contacting the absorbent solution with the gaseous effluent. The absorbent solution comprises water and a corresponding to the particular nitrogen-containing compound of formula (i) c - below, the n, n, n ', n' - tetramethylhexane - 1,6 - diamine, and has a small corrosive power screw - to - screw low-alloy steels component the surfaces of the equipment of de-acidifying.
