Research On Naphtha Separation Technology Simulation Calculation And Modification Of The MTG

MGT is one of the methods to make gasoline from coal. Because of the methanolmarket saturation and over-capacity of methanol production, JAMG coal-to-oil factorydeveloped MTG technique to make gasoline from coal. After two years’ test, The output ofgasoline could reach80,000-100,000tons every year normally. However, crude gasolineseparation process in MTG separation system is so lagging that it becomes an obstacle forgasoline production, the loss of crude gasoline. It also will have a bad effect on the onemillion tons of coal-to-oil project which prepare to start in2015.After investigation the production of coal refinery, the thesis concentrates on theadjustment of research result on the optimal data of MTG operation, the simulation ontransformation of crude gasoline separation and the influence of changing output/quality oflight petrol during the process of transforming crude gasoline separation. The result inJAMG coal-to-oil factory finds that1.the most suitable temperature, the optimal feed rateratio and catalysis time2.when using packing tower instead of plate tower in crude gasolineseparation, the scale of production has expanded and quality of light petrol has improved, atthe same time, the energy consumption has reduced and the output has increased. After morethan two years of operation, the feasibility of the MTG technology has been verified. Usingrich resources of inferior coal in Shanxi province, we can produce clean gasoline such assweet gasoline, white gasoline and low olefin gasoline with MTG technology. It willalleviate the tense of petroleum resources in and make China’s methanol processing havebroader market. It also will be helpful for the efficient use of Shanxi rich high-sulphuranthracite coal resources and will have good industrial application prospect and economicbenefit.
