Objectives
After completion of the module, students should understand the following:- basic concepts related to separation processes;
- fundamental theories related to the separation processes;
- methodologies for designing simple separation devices.
Learning outcomes
On completion of the module students will be familiar with essential aspects of gas-liquid separation by absorption/desorption and distillation. They will understand the underlying physics associated with separation processes, including analogies between mass, momentum and heat transfers and be able to design absorption and distillation columns, falling film column using established theoretical approaches.
This module also considers a number of advanced concepts, such as non-isothermal absorption and mathematical modelling of mass transfer in falling films for the case of slow flux within the film and uniform interfacial solute concentration.
Skills outcomes
- Ability to understand underlying physics associated with separation processes
- Methodologies for designing devices for separation processes
- Transferable skills in linking fundamental theories to real world processes
- Written communication
- Critical reasoning
- Time and self management
