| Summary | The aim of this module is to deepen the students' knowledge of the unit operations with a focus on distillation, absorption, adsorption, and humidification and drying processes. This supports study of Chemical Engineering Design 3 in 3rd year and the Design courses in 4th year. This course draws on the concurrent course in Heat, Mass and Momentum Transfer, which gives the necessary foundations in mass transfer theory, and also on the previous material in Separation Processes 2 which should have imparted an understanding of the basic graphical methods in binary distillation and absorption as well as the foundations of mass and energy balances. The present lectures will explore efficient short cut methods for multicomponent distillation, absorption, stripping, adsorption, humidification and drying processes. Both continuous and batch wise operations will be described through appropriate mass and energy balances and relevant graphical methods. The features of the two main types of equipment for these operations, i.e. trayed and packed towers, will be described and compared. Rate-based mass transfer operations for packed columns will be introduced and employed to design equipment for a range of operations in Chemical Engineering. Finally, the analogy between all the different unit operations covered in the course will be highlighted. |

Learning Outcomes
On completion of this course, the student will be able to:
- Apply the principles of mass, heat transfer and thermodynamics to design a range of unit operations of relevance in chemical engineering;
- Use short cut and graphical methods in design of multicomponent distillation, absorption, stripping, adsorption, humidification and drying operations;
- Analyze critically advantages and disadvantages of various design options and parameters (stage vs. packed columns).
