| Summary | Separation processes introduces an equilibrium stage approach to absorption/stripping, distillation, solvent extraction. Graphical methods are introduced as well as the concepts of minimum number of stages, minimum solvent or stripping agent rate and minimum reflux ratio.
The concept of humidity and the use of psychrometric charts are introduced.
In addition, training in group and collaborative working and communication skills is undertaken. Two laboratory sessions on separation processes are undertaken as part of this course. |
| Course description |
Lectures
The following subjects will be covered during the course:
1. Descriptions of separation processes, stages, cascades, co- and countercurrent flows.
2. Phase equilibrium: gas-liquid, liquid-vapour etc. vapour pressures and relative volatility.
3. Material balance calculations on separation cascades. Mole fraction and mole ratio coordinates, graphical representation, the operating line.
4. Effect of L/V ratio in absorption. Minimum L/V ratio. Stripping and minimum V/L.
5. Distillation: rectifying and stripping sections, material balances. Constant molal overflow.
6. Balances over top plate/condenser and bottom plate/reboiler.
7. Feed plate location and the q-line. McCabe-Thiele construction.
8. Minimum reflux ratio and minimum number of stages. Fenske equation.
9. Partial condensers, multiple feed/product streams.
10. Stage efficiencies and design of plate columns. Selection of reflux ratio.
11. Use of triangular diagrams for ternary systems. Phase boundaries and tie-lines. Solvent extraction.
12. Overall mass balance and sum point.
13. Stage-to-stage mass balance and difference point. Stagewise graphical solution. Minimum solvent:feed ratio.
14. Solvent extraction equipment.
15. Absolute and relative humidities, wet and dry-bulb temperatures, specific volume and enthalpy of humid air.
Laboratories
Students will work on two of the following:
1. Othmer Still
2. CO2 Absorption in Packed Columns
3. Humidification/Drying
4. Continuous Liquid-Liquid Extraction

Learning Outcomes
On completion of this course, the student will be able to:
- Perform graphical or algebraic design calculations for binary distillation, absorption from insoluble carrier gas into a non-volatile solvent, desorption from non-volatile solvent into an insoluble carrier gas and solvent extraction cascades for type II systems.
- Select feasible solvent/stripping agent rates and reflux ratios.
- Describe the principles by which economic reflux ratios are selected.
- Determine the properties of humid air using a psychrometric chart.
