Complex Technology

As a combination of divided wall column (DWC) and reactive-distillation column, the reactive divided wall distillation column is a highly complex technology that reaction and separation can occur simultaneously, which can reduce the energy consumption and decrease the costs of captial and operation. This new process was simulated with PROⅡ software and mini plant experiments were implemented. In addition, we investigated the influences of reflux ratio, liquid distribution ratio and molar ratio of ester in water on the conversion rate of methyl acetate and the purity of the product respectively. It could be seen that the trend from experiments was suitable with simulation results.

Hydrolysis Of

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%.
