- Abstract
The reboiler of process water stripper in an ethylene plant had internal leakage after only one year of operation, which affected the safety, stability and long-term operation. The reboiler was inspected through macro inspection and electromagnetic eddy current scanning, and corrosion analysis was conducted from the aspects of scale sample composition, process medium, operating conditions, equipment structure, etc. It was determined that the cause of leakage was the presence of corrosive medium in the process water system. At the same time, the unstable operation of the process anti-corrosion measures made the process water system acidic or alkaline corrosion environment, which led to severe scaling of the heat exchange tubes, thus forming local corrosion under the scale and crevice corrosion, which aggravated the corrosion of the tube bundles. Combined with the actual working conditions, it is suggested to strengthen the refined management of process anti-corrosion measures, improve the equipment structure, standardize the process operation, so as to inhibit corrosion leakage.
