Methanol distillation process through the material balance and energy balance and heat exchanger design and selection of control in the industrial production of methanol distillation tower role, access to material conditions, plate number and other relevant parameters of the calculation. Finally draw the process flow chart, flow chart with a control point of materials, equipment layout drawings and equipment.
