Optimizing And Investigating Of Catalytic Reformer Plant's Product And Energy Consumption

The catalytic reformer plant of the No.1 Refinery of DaQing Refinery and Chemical Company, the original designing process capacity is 150kt/a, designed by CPCC LuoYang Designing Institute. Constructed in April 1993, started-up in November 1994, fed up with overhead straight-run gasoline of atmosphere and vacuum distillations.The process capacity was increased to 350kt/a by transforming from April to September in 2002. It adopted fixed bed semi-regeneration catalytic reforming technology and platinum-rhenium reforming catalyst, fed up with the mixture of overhead straight-run gasoline of atmosphere and vacuum distillations and hydrogenated gasoline and high research octane number (RON) reforming gasoline, provided the material for aromatic extraction unit and offer hydrogen byproduct to hydrotreating unit. High RON reforming gasoline (more than 95#) has been produced since it put into production in October, 2002.The quality and output of high research octane number, the quantity and purity of hydrogen from the catalytic reformer plant is vital to the harmony of the whole Refinery's environmental protection gasoline and the producing of high quality gasoline. Its production target affect the production operation of the whole refinery directly. The plant is operated by the former experience at the present time and the yield of gasoline can not be rationing predicted. Some people have done a lot of works about the plant flow imitation and operation optimizing. But it is rare reported about making production plan, optimizing decision and the work from determining the nature to the rationing. The ration relations is obtained by building mathematic models. Achieving scientific management, using material resources maximum, obtaining the maximum economic benefit with no increasing costs.The mathematic model was established based on the process data in 2005 by way of linear regress for given dependent and independent variables with SPSS software, in order to enhance the total liquid yields, and to reduce the energy consumption of the unit.The test and analysis results indicated that the model was accorded with practice production. The model has given a scientific forecast for the total liquid yields and energy consumption respectively. It can guide the operating and optimizing of the plant, change the situation that using the former experiences. It could be used to guide the unit operation and provide a dependability for making the production project at the same time.
