| Abstract: | The contents of sulfur,chlorine and other impurities were relatively high in the mixed feed of a 1.0 Mt/a gasoline and diesel hydrotreating unit at a refinery.Corrosive medium generated in the hydrogenation reaction caused severe corrosion of locking ring heat exchanger in the cooling system,as well as high pressure air cooler.In order to solve the above problem,causes,affected areas and influencing factors of the corrosion were analyzed from aspects of raw oil properties and corrosion mechanism.Finally,corresponding protective measures were raised based on the analysis results. |
