The image below shows the corrosion condition at the top of an atmospheric pressure tower in the petrochemical industry. The operating conditions are a pressure of 0.2 MPa, a feedstock of crude oil, a temperature of 360 degrees, and a material composition of 16MnR. The corrosion condition throughout the tower is more severe at the top than at the bottom, primarily due to the corrosive effect of a mixture of hydrogen sulfide, hydrogen chloride, and water. Therefore, attention should be paid to the corrosion at the top of the tower during equipment management.
