Doherty, M F

New techniques are being developed to aid in the design and synthesis of multicomponent, nonideal and azeotropic separation systems. The technique being developed is based on the concept of a residue curve map. These maps represent the fundamental phase-equilibrium behavior of the mixture in a way which is uniquely suited for separation-system studies. The maps provide information for discriminating between feasible and infeasible column sequences. New design tools have also been developed for calculating such quantities as minimum reflux ratios for azeotropic mixtures. In this report, new techniques are presented for analyzing heterogeneous azeotropic distillations. This research is in line with the proposed work described in the original grant proposal. The ultimate aim of this research program is to develop a comprehensive body of theory which will result in automatic computer procedures for synthesizing optimal separation sequences for multicomponent azeotropic mixtures. 10 refs., 3 figs.
