Optimum And Inquiry About Heavy Oil Yield Of IDW Plant 200SN BaseOil

20â…¹104 t/a IDW plant of DaQing Refinery and Chemical Company is the first plant which uses the IDW patent technology of America Chevron to produce high viscosity index, low pour point,high quality base oil in China .Since starting up in 1999,the yield of 5.0 cst heavy oil of 200SN is far different from the design value, and the yield is the benefit point of the plant.The thesis analyses the HDT reaction, the IDW reaction,the HDF reaction ,the property of the feeds, the property of product, finds out seven factors which affect each other ,plurality linear regresses the relative factors which affect 5.0 cst heavy oil yield by the log and the statistics analysis software SPSS, sets up mach model, seeks the method which quantitative optimizes operation parameters and forecasts product yield.By statistics test and practice test of the building model, according with production practice, changing operation parameters and optimizing operation, changing the former experience operation into quantitative guide operation and forecasting the production yield at the same time.
