Abstract A comprehensive survey on the causes of the leakage of the top air cooler of a hydrogenation-type sour water vapor stripping unit, covering aspects such as the process and equipment in question. The air-coolant of the top cooler of the sour water vapor stripping unit consists of H2O, NH3, H2S, NH4HS, and other chemical substances. The failed tube bundles were examined by means of macroscopic observation, metallographic microscope, SEM, and XRD in terms of the microstructure and composition of the tube steel, morphology and composition of corrosion products etc. The results indicated that the hydrogenation-type sour water vapor stripping unit contained higher concentrations of NH3 and H2S, leading to erosion-corrosion that caused progressive thinning of the inner wall of tubes and exacerbated the issue of corrosion and leakage. Analysis revealed that the main cause of the leakage for the air-cooled system was identified as the formation of solid deposits NH4HS on the inner wall of the tube bundle due to condensation, which leads to non-uniform flow velocity of the coolant in the tube, thus leading to localized erosion-corrosion. Finally, corresponding counter measures were also proposed.
