The course aims to give students knowledge and understanding of how larger process systems behave and are operated and controlled. Focus is being placed on the stability of feedback control loops and on advanced control strategies aiming at enhancing safety and operability. Specific cases across the safety hierarchy (basic and advanced process control, alarm systems, emergency shutdown and interlocks, etc.) are addressed.
|Session||Second Sub Session||Credit Points||15 credits (7.5 ECTS credits)|
The course focuses on process operability and safety. The concept of process stability is introduced with a particular focus on controlled processes. Various techniques and criteria are presented, such as frequency response and root-locus analysis, that are used to study the stability of a variety of controlled systems. The interface of automatic process control and process safety is introduced by looking at advanced control strategies like cascade, selective, split-range and ratio control. The safety issues encountered in transient operations are addressed and the use of alarm and interlock systems to address these is discussed. Recommended textbooks are the following:
• Carlos A. Smith, Armando B. Corripio, Principles and Practices of Automatic Process Control, Wiley, 2005.
• George Stephanopoulos, Chemical Process Control: An Introduction to Theory and Practice, PTR Prentice Hall, 1984
Information on contact teaching time is available from the course guide.
1st Attempt: 3-hour written examination (80%); continuous assessment (20%).
The re-sit will comprise of re-doing the failed element/s (exam and/or coursework assessment/s) from the 1st attempt with a maximum CGS mark of D3. The marks for other elements (successfully passed) will be carried over. Resit mark of either RP or RF will be recorded.
Solutions to tutorials are provided.
Feedback is given in the form of discussion with course tutors in contact sessions and on VLE and return of continually assessed work.
