Content	Chapter 1. Absorption and Stripping (5Weeks) - General information on absorption and stripping (absorption, desorption, classification of the main types of absorbers) - Physical absorption: analysis of an absorption column (liquid-gas equilibrium, solubility of gases as a function of pressure and temperature, material balances, minimum liquid flow rate and operating flow rate, theoretical and real stage concepts, Mac Cabe and Thièle method, theories of transfer between phases, concept of transfer units) - Absorption with chemical reaction (material transfer in the presence of an irreversible chemical reaction of order 1.1). - Stripping: analysis of a desorption column (material balances, minimum liquid flow rate and operating flow rate, theoretical and real stage concepts, Mac Cabe and Thièle method). Chapter 2: Liquid-liquid extraction (4 weeks) - Partition coefficient, selectivity, different types of diagrams. Equipment used in continuous and discontinuous extraction. Partially soluble solvent: multi-stage co-current and counter-current extraction (ternary diagram). Insoluble solvent: multi-stage co-current and counter-current extraction (Mac Cabe and Thièle construction), extraction with double feed, extraction with reflux. De-extraction and solvent recycling, choice of de-extraction phase and concept of efficiency. Chapter 3. Distillation (6 weeks) - Continuous distillation (Ponchon and Savarit method, distillation of complex mixtures). Batch distillation. - Sizing a distillation column.
