Abstract
When Puguang gas field in non-normal production of hydrogen sulfide emissions from the combustion generates sulfur dioxide, in order to prevent its impact on the environment, the need for its emergency absorption. Used static weight-loss method study of A3 steel, 304 stainless steel, aluminum, H62 copper in 10% of (NH4)2SO3 solution, 10% of NH4HSO3 solution, and the mixed solution of 10% (NH4)2SO3 and NH4HSO3 respectively, optimized absorption system of material, and using the electrochemical impedance spectroscopy and anodic polarization curve analysis of several kinds of material in the absorption product solution of the corrosion condition. The results showed that 304 stainless steel corrosion resistance of the best, in 10% of (NH4)2SO3 solution, 10% of NH4HSO3 solution, and the mixed solution of 10% (NH4)2SO3 and NH4HSO3 respectively.
