Abstract: In the light of dew point corrosion hidden danger happened at the hydrocracking reaction system,data simulation prediction is performed by means of Aspen Plus chemical software,and the dew point temperature of reaction effluent is proposed for a high pressure system.The effective technical transformation measures such as forward water injection point and equipment material upgrading are adopted to reduce the dew point corrosion probability of high-pressure heat exchanger and other conveying equipment,improving the security and stability of hydrogenation unit operation.The method can be extended to the similar hydrogenation of dew point corrosion failure prediction and protection.
