【Chemical Engineering Operations】Distillation Column Operation

This post was last edited by Xiao Gong 1985 on 2016-3-18 at 13:48. The C4 isobutane removal column in our company is designed with two sections, A and B; currently, the purity of the products at the top and bottom of the column is often decreasing. I would like to know what considerations should be taken into account when operating a distillation column that has such A and B sections (I always feel that the material inflow and outflow of the tower are unbalanced.)
Pay attention to the temperature difference and pressure drop; a small temperature difference indicates that the purity should vary little, while a large pressure difference may be due to an imbalance in the material flow
There is no difference in the operation between two towers and one tower; a decrease in product purity may be due to problems with your operating parameters
