Component-order regions

As far as Eqs. (5.15) and (5.16) should be valid for the points of trajectory located inside concentration simplex, the whole trajectory of the section from tear-off point to point of junction with the trajectory of the second section should be located in one region of section sharp split Reg or Reg. For each sharp split region, Reg or Reg consist of quite definite component-order regions... 

Figure 5.10. Component-order regions Reg, trajectory tear-off regions Reg and Re , and sharp split regions Reg and Reg (hatched for bottom section and shaded for top section, hatched and shaded for two section) for the acetone(l)-chloroform(2)-methanol(3) mixture for splits (a)l,3 1,2 (Reg / and Reg j ) and (b) 2,3 1,2 (Reg ...

Can the top product of the column contain components 4, 5, and 6 if in face 4-5-6 there is component order region Reg Can the bottom product contain components 3 and 4 if at the edge there is segment RegJ ... 

Stationary point of the bundle located in face 2-3-4 this stationary point is located in component-order region where component 1 absent in face 2-3-4 is not... 

Component order region (Reg ) region of concentration simplex in which points component volatilities are in the same order Ki>Kj>Kk). 

Cocrystallization. An additional factor that is operable in some cases involves the ability of the ingredients of a mixture to cocrystallize. These components cannot then demix since portions of each are anchored in the ordered regions in which they both participate. This may be particularly useful for hydrocarbon polymers where favorable enthalpies of mixing do not exist. 

In order that this movement of an amount dn, of component / from region A to region B occurs spontaneously (Frame 14, section 14.4) then dG would negative. This, in turn, would require (comparing equation (29.3) with equation (27.13), Frame 27) that ... 

Figure 4.8. Regions of reversible (shaded) and regions of component order Reg, and Reg (a) rectifying section, and (b) bottom section. Dotty line, separatrix thin lines, a-lines Regjg (region in which component 2 is heaviest) and Reg g (region in which component 3 is hghtest), darker shaded.

Figure 4.8 shows the regions of components order Reg d and of reversible distillation Reg gv or Reg g for this example. In all points of one trajectory in Fig. 4.7b, liquid-vapor tie-lines are directed from one and the same point of the r< -...
