摘要：Corrosion in desulfurizer-H2S-CO2-H2O system was investigated by static weight loss test. The corrosion data for JPE-7 system were compared with those for MDEA and MEA system under the same conditions. The results indicated that the new desulfurizer JPE-7 system was generally less corrosion to carbon steel than MDEA and, MEA system. The order of corrosivity of the desulfurizer system is JPE-7 < MDEA < MEA. With the acid gas loading, especially the CO2 loading increase, the corrosion rate increases. The chloride anion in desulfurizer solution contributes greatly to corrosion. The higher the solution temperature, the more the corrosivity of desulfurizers.
