| Description:
| Aims: To give a critical analysis of chemical and physical interactions in catalytic processes, to introduce analysis tools and models for a variety of reactors employing catalysts in solid form and to present the basis and value of residence time distribution (RTD) techniques. To introduce the principles and practices underlying, (a) the selection and sequencing of complex separations, and, (b) the design and operation of advanced separation processes based on adsorption, membranes, crystallisation and reactive separation. Learning Outcomes: After successfully completing this unit the student should be able to analyse reactions, mass transfer effects and deactivation in catalytic processes; analyse and design and wide variety of reactors, apply residence time distribution techniques, apply fundamental scientific and engineering principles to determine optimum separation sequences for complex multicomponent feedstocks; design and analyse the performance of adsorption-based separations; design and analyse the performance of membrane-based separations; design and analyse the performance of crystallisation-based separations; design and analyse the performance of advanced solvent extraction processes. Skills: Advanced numerical, theoretical and computational methods. Problem solving. Taught/facilitated and assessed.
