Synthesis of Separation Flowsheets for Multicomponent Azeotropic Mixtures on the Basis o the Distillation Theory. Presynthesis: Prediction of Feasible Product Compositions

摘要

A general approach based on the theory of distillation-trajectory tearing off is adopted in the syn- thesis of optimal separation flowsheets for multicomponent azeotropic mixtures. The first stage of the synthe- sis-presynthesis-is considered, at which feasible product compositions are predicted for the separation in a simple column, a two-feed column, and a column with a decanter.
