Modelling of Separation Processes
|Course code CHEE3731||Units 10||Level 3000||Faculty of Engineering and Built EnvironmentSchool of Engineering|
Provides an understanding of simple model development, transfer functions, block diagram representation and analysis, and simple control systems. Most of the model development is based on simple unit operations and separation processes. Also provides students with the fundamentals necessary to design or evaluate a broad range of separation processes.
Available in 2015
|Objectives||On completion of this course, students should:|
1. be able to suggest a separation method for a particular process requirement;
2. be able to make suggestions on the type of equipment required;
3. be able to make suggestions regarding the size, operating parameters, etc. based on design considerations such as throughput;
4. know the fundamentals of process modelling and be able to work with commercial modelling packages.
