Chemical engineering separation operations including humidification/dehumidification, drying, membrane separations, leaching and washing, crystallisation, ion exchange, distillation, gas absorption and liquid-liquid extraction.
An introduction to the fundamental principles of equilibrium conditions and heat and mass transfer.Consistent methodology is applied to demonstrate how fundamental principles are used to design and operate separation unit operations.• Fundamental principle (unit operation)• Separation physical challenge• Separation process metrics• Solubility (Washing and leaching)• Equilibrium stages (Washing and leaching)• Counter-current, cross-current, and co-current design (Washing and leaching)• Vapour-liquid equilibria (Distillation)• Operating equations (Distillation)• Mass transfer limitations (Gas Absorption)• Steady-state processes (Membranes)• Heat transfer (Drying)• Humidity (Humidification)• Combined heat and mass transfer (Drying and Humidification)• Roles of separation engineers (Industrial interviews)• Project management (Optional)
Students should:Fully understand physical equilibria.Understand the process metrics for separation process design.Understand equilibrium stages.Design staged separation processes.Understand how heat and mass transfer limitations affect separation process operation and design.Gain insight into professional separation engineering roles.Improve formatting and written report skills.Be able to identify and apply separation design principles in any separation process.
Students must attend one activity from each section.
36 lectures, 3 assignments and 1 test.Attendance at all lectures is highly encouraged. Students who do not complete all assignments and the exam are much less likely to pass.You have optional involvement in using a project management software to organize your ENCH396 schedule and workload.
