RESEARCH OF THE EFFICIENCY OF CORROSION PROTECTION OF THE MARZA-1 INHIBITOR IN THE MEDIA H2S, CO2 and H2S + CO2

Abstract

For the first time in the laboratory, the effectiveness of protection of the MARZA-1 inhibitor from corrosion in aggressive environments with hydrogen sulfide, carbon dioxide and carbon dioxide in combination with hydrogen sulfide was investigated. Laboratory tests were carried out in a solution of an analogue of formation water MI. The experiments were carried out for one and ten days at an inhibitor concentration of 3.0, 5.0, 7.0, 10.0 mg/l. The results of numerous laboratory studies have shown that in all cases the protective effect of the MARZA-1 inhibitor increases with an increase in its concentration. The greatest effect was recorded at 10 mg/l for 24 and 240 hours. This effect was 98.0 and 95.7% in a hydrogen sulfide environment, 94.80 and 94.83% in a carbon dioxide environment, 96.8 and 99.23% in a mixed environment (H2S + CO2).
