Abstract


Production methods and application prospect of methyl tertiary butyl ether(MTBE) andtert-butyl alcohol(TBA) at home and abroad is introduced in this paper firstly, and rfom theangle of environmental pollution and economic benefits, the problems in current productionare pointed out. On this basis, this paper proposes a co-production technology of methyltert-butyl ether and tert-butyl alcohol.In this paper, using pro/II sotfware with annual output of60000tons of MTBE plant yieldprocess as a model for the whole process simulation. Firstly, it finds the appropiratethermodynamic method: modified SRKM equation, by the physical properties of selectionand contrast the simulated data with the actual production data method. Then, it carrys onsensitivity analysis to operating conditions of each of the major unit of equipment to ifnd asuitable joint process of optimal operating conditions. By contrast, it analysises the energysaving effect of MTBE catalytic distillation unit,and evaluates its economy; it makes theexisting MTBE device diagnosis, analysis, and pointed out the reasons of energy use is notreasonable, and carires on the comprehensive optimization; following the pinch pointtechnology criteiron, the existing heat exchanger network was optimized. Optimized heatexchange network without any increase in cost of investment in equipment can save heatingutilities on the basis of the volume of773.445kW,773.445kW cooling utilities engineeirngquantity. The heat exchanger network atfer optimization has remarkable energy-saving effect,energy saving scheme is feasible and it has certain guiding significance for the device.Finally, this paper puts forward a co-production process of MTBE and TBA,and rfom twokinds of process operating conditions and mateiral balance, it evaluates the feasibility ofco-production. This technology makes tfill use of advantages of closely integrated reaction andseparation, both substitutes for MTBE production, and can solve problem of anhydroustert-butyl alcohol production.
