Abstract

Multicomponent distillation programs in general use are seldom capable of describing systems whose flow patterns differ from the conventional counter-current. However, these programs may be extended to include pumparounds or interphase mass transfer by algorithms which require neither additional internal iteration steps nor repetitive solutions. For a pumparound, a recursive procedure is developed to use the conventional Thomas Algorithm modified by an additional multiplier in the second step. To describe interphase mass transfer, the solution to the set of material balance equations requires a recursive technique in which the definitions for the algorithm alternate for successive stages. The use of recursional procedures is demonstrated on a multicomponent distillation column simulation. © 1977.
