| Abstract: | The cooling water system of lithium bromide refrigeration train in LPG fractionation unit suffered severe corrosion, which led to frequent corrosion leakages in the cooking water equipment. The analysis of the corrosion mechanisms concluded that the desolved oxygen in the cooling water was the major culprit for the electro-chemical corrosion of the equipment. The application of both physical and chemical measures like installation of multi-function electronic defouling instrument and injection of fouling inhibitor etc have solved the corrosion problem of the cooling water system. |
