Abstract The xorrosion mechanism of REAC for hydrocracking and the same status in its upper and lower pipe system were discussed.The paper introduced the aggradation rules of NH4HS,NH4Cl,the configaration and performance of protecting film combined by FexSy,the operating cinditions and influence of other chemical factors.An example of the hydrocracking unit for processing high sulfur oil, which was found in processing capacity enlarged and reconstructed in Zhenhai Refining & Chemical Corporation Ltd,was shown. The failure of such corrosion mechanism was analyzed in detail. The optimal operating method was presented.

Key words: hydrogenation reactor air - cooler system corrosion mechanism corrosion failure
