Abstract

While usage of volatile corrosion inhibitors (VCI) is one of the effective methods in corrosion protection for rough, complicated and multi sub-component equipment, traditional protecting methods show no obvious efficiency. The results of an applied research at Ca Mau Power Plant and Dung Quat Refinery showed that volatile corrosion inhibitors have an ability to absorb on metal surface to prevent corrosion with high efficiency of above 80% for copper coupons, above 85% for steel coupons in electrical boxes and up to over 90% for steel coupons attached to flanges of air exposed pipeline.
