Abstract

A dynamic model has been developed to study the dynamic behavior of multi
component batch extractive distillation column. The set of equations
governing (material bvalance, heat balance, summation of mole and
equilibrium equations) which represent the dynamic model are solved to give
the temperature and composition profile. Eigenvalue method was used to
integrate the stiff ordinary differential equations.
Matrix method was used to solve many equations simultaeously to redefine
the column parameters during program run. Newtons algorithm was used to
calculate the plate temperatures on each tray.
The calculations and simulations in this paper were obtained by using
MATLAB environment, version 6. The result of the proposed model are
compared with experimental result taken under the same operating
conditions. This model shows good agreement with experimental results and
explains features of the batch extractive distillation process.
