| 摘 要： | 普光气田在非正常生产时排出的硫化氢经燃烧会生成二氧化硫,为防止其对环境的影响,需要对其进行应急吸收。采用静态挂片失重法研究A3钢、304不锈钢、铝、H62铜等四种材质在10%的(NH4)2SO3、10%的NH4HSO3以及10%的(NH4)2SO3和NH4HSO3的混合溶液中的腐蚀情况,优选了吸收系统的材质,并利用电化学阻抗谱和极化曲线分析了几种材质在吸收产物溶液中的腐蚀状况。结果表明:在10%的(NH4)2SO3、10%的NH4HSO3以及10%的(NH4)2SO3和NH4HSO3的混合溶液中,304不锈钢的耐腐蚀性能最强。

| 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, aluminium,H62 copper in 10 % of (NH4)2SO3, 10 % of NH4HSO3,and 10 % (NH4)2SO3 and NH4HSO3 of mixed solution, 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 stee corrosion resistance of the best, in 10 % of (NH4)2SO3, 10 % of NH4HSO3,and 10 % (NH4)2SO3 and NH4HSO3 of mixed solution. |
