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 at least one nitrogen-containing compound particular corresponding to the formula (i) c - below, and has a small corrosive power screw - to - screw low-alloy steels component the surfaces of the equipment of de-acidifying.
