Design of Catalytic Divided Wall Column
The Catalytic Divided Wall Column (CDWC) for hydrolysis of methyl acetate (MeAc) is designed and optimized. Distillate rate and side rate of CDWC are used to maintain the desired product purities, and the minimum reboiler duty is obtained by changing the reflux ratio and vapor split ratio. The result shows that the new process can save energy consumption by 20.1%.
