Abstract :
A model of a distillation column is developed that includes component and enthalpy balances, equilibrium relationships, variable pressure and complex tray hydraulic relationships. The model is incorporated into a computer program that produces Bode plots of the transfer functions between any input variable and any column variable. The paper includes examples of the use of the program to study column dynamic response and control loop interaction as a function of frequency.
