Distillation: Control Systems

By the end of this course you will be able to: Explain what is meant by material balance energy balance steady-state operation and a process disturbance Identify typical variables and control loops for material balance and energy balance Describe how a typical distillation tower control system responds to a process disturbance and to an increase in bottom temperature Explain how the following conditions affect the composition of a distillation systems overhead and bottoms products: increase in bottom temperature decrease in bottom temperature and change in external reflux Describe the following related to product composition: the difference between direct and indirect composition measurements and how a typical distillation tower is operated to maintain product specifications
