Two time delay compensation techniques, the Smith predictor and the analytical predictor, are used for bottom composition control of a pilot scale methanol-water distillation column. The closed-loop performance of the two predictor schemes is compared to that for a proportional-integral controller i
Sin-mary--The theory developed in part I is applied to the following two-variable control systems for distillation columns: (a) pressure control by condenser cooling, and temperature control by reboiler heating; (b) overhead quality control by reflux, and bottom quality control by reboiler heating.
