Three-component mixtures possible product regions

Figure 4.11. Sharp reversible section diagrams of some structures of three-component mixtures. 1,3.4a,..., classification according to Gurikov (1958). Double line, possible composition of overhead product Reg thick solid line, possible composition of bottom product Reg dotted lines with arrows, reversible section trajectories 123,132,312. regions of component order Reg dotty lines, separatrixes thin hues, a-lines.

The location of trajectory bundles and possible product composition segments at reversible distillation of three-component mixtures determines the location of trajectory bundles, and of possible product composition regions of multicomponent mixtures and the locations of trajectory bundles of real adiabatic columns. 

Determination of possible composition regions Reg Reg of top and bottom products at reversible distillation of all three-component constituents of initial mixture.
