| Prerequisite |
| The introductory cours about distillation taught in 2A, allow having the thermodynamic basis of liquid-vapor equilibrium. |
| Course Objectives |
| Separation processes account for a large part of the investments of an industrial chemical unit. The existing techniques are numerous and depend in particular on the phases of the system under consideration. In this course, after an overview of the various existing techniques, the most widespread petrochemicals and depollution will be studied such as distillation, liquid-liquid extraction and liquid-gas absorption. The objective is to improve the knowledge of existing techniques and to control simple sizing tools. |
| Syllabus |
| The tools for sizing distillation columns (number of trays, reflux rates, heat to be supplied, among others), which represent a key tool in a refinery, will be seen in detail. In liquid liquid extraction, which is also widely used in refining, the thermodynamic bases of equilibrium between phases will be the starting point for unit sizing (number of trays, minimum solvent flow). Finally, these design principles will be applied to liquid-gas absorption columns after brief reminders of thermodynamics. |
| Practical work (TD or TP) |
| The courses will be accompanied by practical exercises. The 3 TPs focus on distillation (batch and continuous), liquid-liquid extraction on a perforated plate column and liquid-gas absorption on a packed column. |
| Acquired skills |
| Sizing techniques, Material balance, Heat balance, Knowledge of distillation column technology |
