| Summary | One half of this course covers adsorption and crystallization processes. The section on adsorption processes is aimed to understand how to design and operate a cyclic adsorption process and estimate its performance. To this end, we apply a mathematical method called Equilibrium Theory to various adsorption systems and learn a graphical method to construct a cyclic adsorption process cycle. The crystallisation process section comprises solid/liquid phase equilibrium, mass and energy balances and the analysis of a crystalliser (MSMPR).
The other half of the course, on distillation, comprises a discussion of composition and temperature profiles in ideal distillation columns, followed by examples and purposes of non-standard configurations and energy integration schemes for distillation. The modelling basis for tray-by-tray simulation of distillation columns is followed by a review of how azeotrope - forming mixtures can be separated. Topics include the causes of non-ideality, extractive and azeotropic distillation and composition trajectories. |

Learning Outcomes
On completion of this course, the student will be able to:
- Design stepwise configuration of a multi-column cyclic adsorption process by a short-cut method. - Describe how various adsorption processes work in the context of actual industrial processes containing the adsorption.
- Describe how to configure acid gas removal processes having absorption columns. - Construct the mass and energy balances around a crystalliser and design a crystallizer given the target specification.
- Recognise design faults from column temperature/composition profiles in distillation columns for ideal binary mixtures, Describe tray by tray distillation methods. - Discuss heat integration for distillation, citing and explaining a number of strategies.
- Describe and discuss the causes and consequences of non-ideality in distillation, with particular reference to Hydrogen Bonding. - Explain features of non-ideal distillation profiles and how they differ from ideal.
- Draw flowsheets for and describe details of azeotropic and extractive distillation systems for separating non-ideal systems, including those with azeotropes. - Sketch distillation boundaries for ternary systems, and calculate the consequent limits on separations for azeotropic systems.
