By F. B. Petlyuk
Writing for designers and operators of separation devices within the chemical, pharmaceutical, meals, and comparable industries in addition to software program designers, F.B. Petlyuk offers a transparent, multidimensional geometric illustration of distillation concept legitimate for all sorts of distillation column kinds, splits, and combinations. DistillDesigner software program permits refinement and affirmation of the algorithms of optimum layout. equipment of the overall geometric idea of distillation, encoded in DistillDesigner, offer speedy and trustworthy ideas to difficulties of flowsheet synthesis and to optimum layout calculations.

It is the profile of concentrations of the column section. 6 Minimum Reflux Mode: Fractionation Classes 29 The given trajectory belongs to some trajectory bundle bounded by its fixed points (points Nr− , Sr and Nr+ of Fig. 5a and points Ss and Ns+ of Fig. 5b), the separatrixes of the saddle points S and the sides of the concentration triangle. Knowledge about the regularities of the trajectory bundles arrangement under the finite reflux provides an opportunity to develop the reliable and fast-acting algorithm to fulfill design calculations of distillation to determine the required number of trays for each section.
2b it is clear that, in this particular case, the infinite number of steps and, respectively, the area of constant concentrations appear in the point of tangency of the top section operation line to the equilibrium curve (this point is indicated as xpinch ), but not in the feed point. Such an area of constant concentrations is called a tangential pinch. 3 Geometric Interpretation of Multicomponent Mixture Distillation: Splits June 11, 2004 25 Now, if we consider the tangential azeotrope mixture at x1 = 1 (Fig.
