Rigorous Computation of Binary Distillation Systems
A computation algorithm for the distillation of binary systems based on the concepts involved in the graphical Ponchon-Savarit method is introduced. Equilibrium and enthalpy data are estimated by the UNIQUAC activity coefficient equation. All the parameters of the system (temperatures, enthalpies, flow rates, and composition of the streams in each stage) are computed with much higher accuracies than those obtained by the graphical method.
