摘　　要：讨论了影响环烷酸腐蚀的主要因素后指出:预测原油环烷酸腐蚀性时.酸值是一重要参数.但不是唯一的.油的流速和流态对环保酸腐蚀有重要作用.增加不锈钢中的钼含量.可提高耐环烷酸腐蚀的性能.最后介绍了几种化学试剂的缓蚀作用.The main factors affecting the naphthenic acid corrosion were discussed. It was pointed out that the acid value was an important, if not the only, parameter in predicting the corrosivity of naphthenic acid. Furthermore, the flow velocity and state also play an important role. Increasing the Mo content in the stainless steel could enhance the corrosion resistance of the steel to naphthenic acid. The corrosion inhibition performances of several chemical agents were finally introduced.
