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。 The MMO was applied to the cathodic protection of the crude oil tank outer soleplate. The cathode protection effect of the tank outer soleplate was monitored by using high purity zinc reference electrode and Cu / Cu SO4 reference electrode. From five years of cathodic protection operating data, it can be seen that over 95% of the cathodic protection potentials on the outer tank floor have a negative -0.85V (vs.CSE) and the outer tank bottom plate is in good cathodic protection.
