To develop key concepts in separation processes and mass transfer of relevance to the chemical engineering profession.

Learning Outcomes:
After successfully completing this unit students should be able to:
* Understand steady and unsteady state models for mass transfer across a phase boundary;
* Design a mass transfer controlled packed column;
* Design a batch distillation column operating under constant top product composition conditions;
* Examine reflux and stage requirements for multi-component distillation columns;
* Carry out a detailed design of a separating column.

Skills:
Analysis, design and problem solving.

Content:

* Mass transfer across a phase boundary, including the 2 film theory, penetration theory, Higbie, and Higbie-Danckwerts models;
* Mass transfer coefficients and their use in dimensionless groups and correlations to describe mass transfer;
* The role of mass transfer coefficients in the design of absorption columns;
* Concept of Number of Transfer Units and Height of a Transfer Unit;
* Batch distillation operation with constant top product composition;
* Estimation of the reflux and stage requirements for multi-component distillation processes using the correlations of Gilliland and Erbar-Maddox;
* Detailed distillation column design;
* Operation of multiple-effect evaporators.
