![]() | Aims: 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: * Describe the theory of steady and unsteady state models for mass transfer across a phase boundary and carry out basic calculations; * Design a mass transfer controlled packed column; * Design a batch distillation column operating under constant top product composition conditions; * Determine the reflux and stage requirement relationship for multi-component distillation columns; * Carry out a detailed design of a separating column. Skills: Analysis [T,F,A] Design [T,F,A] Problem solving [T,F,A] 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 and operation; * Operation of multiple-effect evaporators. |
