XX20166 Process dynamics
| Credits: 6 |
| Semester: 1|
|Assessment: CW 40%, EX 60%|
Aims: To provide an introduction to the mathematical description of dynamic processes in chemical engineering, theory and practice of process control. The unit will provide good background in developing dynamic process models, control of dynamic processes and development of complete control systems for chemical and biochemical processes.
After successfully completing this unit students should be able to:
* Develop dynamic models of typical chemical and biochemical engineering problems, including heat and mass transfer, and chemical and biochemical reactions.
* Use Laplace Transform techniques to solve initial value problems.
* Use simulation tools to obtain parameters of dynamic models.
* Design experiments to obtain parameters of dynamic models of physical processes.
* Develop complete control systems for simple unit operations.
* Analyse dynamic behaviour of first order systems, including interacting and non-interacting series
* Understand the concept of stability and its effects on control problems.
Analysis and problem solving (taught/facilitated and assessed).
* Transient material, energy and momentum balances.
* Laplace transforms to solve initial value problems.
* First order systems; first order systems in series; time constant; process gain; transfer function. Use of time, Laplace and frequency domains for analysis of dynamic systems. Stability.
* Feed-back, feed-forward, cascade control; overall transfer function; design and simulation of control systems.
* Case studies: control of bioprocesses, control of non-linear systems.
