Aims: To introduce and develop key concepts in separation processes of relevance to the chemical engineering profession.
Learning Outcomes: After successfully completing this unit students should be able to: * Outline the basic features of membrane processes, distillation processes, absorption processes and liquid /liquid extraction processes. * Select appropriate membrane technology for a particular separation problem. * Understand the operation of single and multistage distillation columns. * Design simple multistage binary distillation columns. * Carry out ternary multistage solvent extraction calculations. Skills: Analysis and problem solving. Content: * Overview of available separation processes; * Fundamental principles of phase equilibrium relationships; * Principles of vapour/liquid equilibrium; * Principles of single stage equilibrium flash; * Principles of multistage contacting, counter-current contacting; * Binary phase diagrams; * Bubble and dew point calculations; * Binary multistage distillation; * Reflux ratio; total, minimum and economic ratios; * Effect of distillation column sidestreams; * Liquid/liquid equilibria; * Ternary phase diagrams; * Classes of synthetic membranes; * Operation of pressure driven membrane processes; * Membrane fouling; * Membrane module design. |
