摘要
采用静态高温高压模拟试验方法对硫脲在高CO2和Cl-环境中缓蚀行为及其对复配缓蚀剂性能的影响进行了研究.结果表明:90℃时,在咪唑啉缓蚀剂中复配入硫脲,有利于提高复配缓蚀效率;在高CO2和Cl-环境中,随着温度升高,硫脲缓蚀效果下降,120℃时硫脲不但没有缓蚀效果,反而加速腐蚀.
A new solid inhibitor of imidazoline was developed, and then a compound of which with thiourea was prepared. The effect of thiourea on the corrosion inhibition of the compound inhibitor on N80 steel was studied in high temperature and high pressure solutions with high content CO2 and Cl^-. The experiment results of corrosion tests showed that thiourea shows benefit to inhibition ability at low temperatures, however at 120℃ thiourea shows hamful to the inhibition effectiveness.
