Abstract: In order to separate the products from catalytic hydrogenation of dimethyl adipate, a three-column continuous distillation process is designed and the related distillation process is simulated by Aspen Plus software. The DSTWU module is employed for simple calculation and the RADFRAC module for rigorously calculation. The effects of the reflux ratio, theoretical plate number and feeding locations are studied and optimized. The results show that the optimal parameters for B1 column, B2 column and B3 column are shown as follows:the theoretical plates are 17, 28 and 11, the reflux ratios are 0.47, 0.94 and 1.73, the optimal feeding locations are at the 10th plate, the 18th plate and the 7th plate, respectively. The mass fraction of methanol, n-butanol, 2-methylcyclopentanol and 1, 6-hexanediol in the product are 99.9%, 99.5%, 95.0% and 99.5% respectively.
