Abstract
Depending on the feed composition, the processing capacity (Cap) of a batch distillation column may be increased by applying another, smaller column (Column1), which can serve as prefractionator or can operate in parallel, independently of the large column (Column2). The two-column processes are investigated with varying the number of trays of Column1 (N1) by rigorous simulation for the separation of acetone-water and water-acetic acid mixtures. The purity of the organic product is specified. Three operational policies are studied: only the large column is operated (Policy I), Column1 is operated either sequentially as prefractionator for Column2 (Policy IIa) or in parallel with it (Policy IIb). All policies are optimised by maximising Cap. The goal is to find the range of N1 for different charge compositions where Cap of the single-column process (CapI) can be increased by applying the smaller column by reaching at least its recovery (I).
