Distillation geometric interpretation

That is why, before we start the examination of the existing distillation process and its geometric interpretation, it is necessary to consider geometric interpretation, of the phase equilibrium. Numerous methods of calculating phase equilibrium are described in many monographs and manuals (see, e.g., Walas [1985]). 

Geometric interpretation is extremely important for the understanding of distillation process. In this relation, binary distillation gives us particularly large possibilities. Only for binary distillation are we able to show in a flat diagram the composition of both liquid and vapor (curves yi - xi). 

Geometric Interpretation of Multicomponent Mixture Distillation Splits... 

Geometric interpretation of distillation process of binary mixtures has been decisive in understanding the subject and the basic principles of the distillation units design development. Geometric interpretation of multicomponent mixtures distillation is also important for deep insight into the pattern of the multicomponent mixture distillation and better understanding of the methods of design of the units used for the separation of these mixtures. 

The solution of Underwood gave impetus to numerous investigations based on this approach. Part of these works was directed to the creation of geometric interpretation of the results obtained from the solution of the Underwood equations system. It is impossible without such interpretation to form a true notion of the general regularities of the distillation process of ideal mixtures. For one-section columns, geometric analysis of trajectories, stationary points, and separatrixes of distillation was realized even before the works of Underwood by Hausen (1934, 1935,1952) on the basis of calculations using the method tray by tray. ...
