Corrosion causes and countermeasures of three-stage condenser tube bundle in sulfur plant
Corrosion occurred both outside and inside the tube bundle of the condenser(E102)in the three-stage condenser of a sulfur plant in a refinery.Through material analysis,metallographic inspection and electron microscope analysis of the condenser combined with the comprehensive judgment of the process flow.The results show that the corrosion perforation of the outer wall of the E102 tube bundle should be caused by the corrosion of dissolved oxygen,and the corrosion property of the inner wall of the tube bundle is the corrosion of the process gas medium in the tube.
