This module is not approved as an Elective

Objectives

- To introduce students to the fundamental principles and practical methodologies for process integration, optimisation and control in the food industries.
- Train student the skills of applying the principles and methodologies to practical applications in the food industries.
- Introduce the state of the art development in the general areas of process systems engineering and control related to food process engineering.
- Prepare students with the background knowledge for employment in the process industries as well as for postgraduate studies and research.

Learning outcomes
On completion of this module, students should have a deeper knowledge of:
- Pinch analysis and process integration and proven techniques in deterministic optimisation algorithms for both linear and nonlinear problems.
- Process control objectives, control system components, feed back control configurations, controller tuning, feedforward and cascade control, process dynamics and model identification and control; control strategies for unit operations, future trends in process control.

Skills outcomes
On completion of this module, students should have the following skills:
- Be able to set energy targets for large complex processes based on thermodynamic principles and make the most effective applications of optimisation in the food process industries.
- Develop control strategies for a given process, read and draw P&ID diagrams, being able to analyse system dynamics and develop appropriate control strategies.
- Understand advanced topics on control.

Syllabus

Process Integration and Optimisation:
- Pinch analysis and process integration: heat-exchanger networks, cascade diagrams, minimum utility loads, pinch temperature, composite curve, number of heat-exchangers, loops and paths, pinch matches, restore the minimum approach temperature.

Teaching methods

Delivery type	Number	Length hours	Student hours
Class tests, exams and assessment	1	3.00	3.00

Tutorial	22	1.00	22.00
Private study hours			231.00
Total Contact hours			69.00
Total hours (100hr per 10 credits)			300.00

Private study

The students are expected to read the recommended textbooks together with the handouts for developing a deeper understanding of the topics covered in the formal classes. They should look at the worked out example problems in textbooks to learn how theory can be applied to solve practical problems. To develop problem solving skills they should independently try to solve the problems given in the problem sheets provided by the lecturers and also textbook exercise problems prior to the tutorial class.

Opportunities for Formative Feedback

Students' progress will be monitored via:
- the extent of participation and response to questions asked in the formal lecture and tutorial classes;
- the attendance in lecture and tutorial classes.
