This module is not approved as an Elective

Objectives

After completion of the module, students should understand the following:
- basic concepts related to distillation;
- fundamental theories related to distillation;
- methodologies for designing simple distillation columns equipped with suitable auxiliary units;
- approaches for modelling simple distillation columns and auxiliary units using relevant software.

Learning outcomes
Students completing this module will:
- be able to appreciate the chemical engineering context of distillation;
- be able to apply the principles of material and energy balance and appreciate the effect of the thermodynamic properties of fluids on the phase equilibrium;
- have a knowledge and understanding of the principles of different types of processes, including continuous and batch operation under steady state and criteria for process selection;
- have a knowledge of the characteristics and essential aspects of gas-liquid separation by distillation;
- be able to carry out equipment design calculation for distillation columns using established theoretical approaches and applying rigorous and shortcut calculations, to deliver required products;
- be able to use relevant software to carry out modelling and simple optimization for distillation columns to meet the requirement for separation;
- be able to identify the objectives and context of the design calculation according to technical requirements, and appreciate the constraints and multiple objectives to reach optimal design.

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
