Abstract | A dimensional time model of the middle vessel batch distillation column ({MVC}) is developed in the {ABACUSS} process modeling environment, and simulations are conducted to validate the theoretical insights developed for the operation of the {MVC} based on a warped time model of the {MVC}. The qualitative dynamics of the {MVC} operated in the presence of linear separation boundaries are validated via simulations conducted on the ternary azeotropic mixture of acetone, chloroform, and methanol. It is also shown via simulation that the separation results obtained from a column with significant but reasonable amounts of holdup on the trays are not significantly different from a column in which holdup in the trays is assumed to be negligible. Theoretical operating policies for separating the azeotrope of acetone and chloroform using benzene as a batch entrainer are also validated using the {ABACUSS} model. Finally, we explore the advantages and disadvantages of different feasible operating policies for separating a mixture of acetone, benzene, and chloroform completely into its constituent pure components. |
