Method for determining influence factor of active sulfide content on naphthenic acid corrosion rate

The invention provides a method for determining an influence factor of the active sulfide content on the naphthenic acid corrosion rate. The influence factor Is of the active sulfide content on the naphthenic acid corrosion rate is as follows: Is = Vs,c/Vs,0, wherein Vs,c represents the naphthenic acid corrosion rate under any active sulfide content, and Vs,0 represents the naphthenic acid corrosion rate when the active sulfide content is zero. According to the method, naphthenic acid corrosion isotherm under different active sulfide contents is used for expressing the influence degree of the active sulfide contents on naphthenic acid corrosion, and a Matlab data fitting and interpolation calculation method is combined, so that the quantitative influence rule of the active sulfide contents on the naphthenic acid corrosion rate is defined; and a necessary theoretical basis is provided for naphthenic acid corrosion prediction model construction under high-speed turbulence. 本发明提供一种活性硫化物含量对环烷酸腐蚀速率影响因子的确定方法，活性硫化物含
