Expansion and energy-saving revamping of No.1 hydrocracking unit

In the revamping of No.1 hydrocracking unit in SINOPEC Zhenhai Refining Chemical Co.,Ltd.,the capacity was expanded from 1.0 million tons per year to 1.2 million tons a year.In addition,others revamps were executed for steam reduction,electric power saving,low-temperature heat utilization,optimization of heat exchange train and heat integration of the unit,etc.After revamping,not only the liquid yields and hydrogen utilization rate are increased,but also the good quality feedstocks can be produced for the ethylene crackers and catalytic reformers.
