摘 要: | 对国内外有关环烷酸腐蚀预测方法的文献报道进行分析得出 :原油的总酸值和硫含量无法准确预测环烷酸腐蚀 ;以环烷酸腐蚀介质中的高压釜失重实验为基础的金属挂片法可提供与环烷酸腐蚀最为直接的参考数据 ,其中腐蚀速率与金属挂片单位面积上失重量的比值 (环烷酸腐蚀指数法 )是目前最好的预测方法 ;其次是与流体流速有关的壁剪切应力比较法

关 键 词: | 原油总酸值 环烷酸 腐蚀 腐蚀速率 壁剪切应力 |

Overview of Prediction Methods for Crude Oil Naphthenic Acid Corrosion |
| |
Abstract: | It is concluded from overseas and domestic reports on the prediction methods of naphthenic acid corrosion that, the naphthenic acid corrosion can not be predicted from the total acid value and sulfur content of the crude oil, the metal coupon testing in high-pressure autoclave weight-loss experiment using corrosive naphthenic acid media can provide the most direct reference data relating to naphthenic acid corrosion, and the best method is the ratio of the corrosion rate to weight loss per unit area of metal coupon (corrosion index) followed by wall shearing stress comparison method related to fluid velocity. |

Keywords: | total crude acid value naphthenic acid corrosion corrosion rate wall shearing stress |
