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 system’s 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
