Mathematical modeling and numerical integration of multicomponent batch distillation equations
G. P. Distefano
Source abstract
Abstract A mathematical model for multicomponent batch distillation was derived, and a FORTRAN IV program was written for solution on a digital computer. The program has been used in the simulation of several commercial batch distillation columns. A calculation procedure for the numerical solution of batch distillation equations starting from total reflux steady state conditions was developed, and the step‐by‐step procedure is presented here. Also included is a discussion of the stability and relative computational effectiveness of various numerical integration techniques when applied to transient distillation calculations. The discussion applies equally well to both batch distillation and unsteady state continuous distillation.
