石油储罐外底板阴极保护工程实例

Cathodic Protection Engineering Example for Oil Tank Outside Floor

将网状贵金属氧化物阳极(MMO)应用于原油罐外底板阴极保护工程中,采用高纯锌参比电极与Cu/Cu SO4参比电极对储罐外底板的阴极保护效果进行监测。从5年的阴极保护运行数据可以看出,超过95%的储罐外底板的阴极保护电位负于-0.85V(vs.CSE),储罐外底板处于良好的阴极保护状态。

Mesh MMO was used as the anode material in the cathodic protection project of the outside floor of the oil tank, and the high purity Zinc and Cu/CuSQ were used as reference electrodes to monitor cahtodic protection results. From the results of 5 years, more than 95 % of cathodic protection potentials of the outside floors were more negative than -0. 85V （vs. CSE）, so the outside floors of the oil tank were in good cathodic protection.
