Optimal simulation system for methanol rectification process

The invention relates to an optimal simulation system for a methanol rectification process of a large-scale coal chemical industry, and provides theoretical guidance for optimization of the methanol rectification process of the large-scale coal chemical industry. The optimal simulation system comprises three parts; the bottom layer of the optimal simulation system is provided with an Aspen Plus simulation file of the methanol rectification process of the large-scale coal chemical industry to provide a process mechanism model and a calculation platform; the top layer of the optimal simulation system is provided with a simulation interface to provide a man-machine interactive window, and the Aspen Plus simulation file of the methanol rectification process of the large-scale coal chemical industry and the simulation interface are linked through a Visual Basic interface program. On the simulation interface, an input parameter of the bottom simulation file can be changed, and a simulation result also can be obtain
