| Abstract: | Based upon the research on the corrosion and corrosion mechanisms of high - pressure air coolers in the hydrotreating unit and through a case study on the hot LP separator gas air coolers corrosion leakage and operating data of a hydrotreating unit in a refinery, the operating conditions and associated corrosion data of the air cooler are analyzed. The main corrosion forms, corrosion factors and corrosion prevention measures of the cooler are studied. |
