AIMS

This subject provides an advanced focus on the heat and mass transport processes that are part of the core knowledge and problem solving skills basis for chemical engineering unit operations. In addition, an advanced understanding of these transport processes will help enable students in the design of larger scale chemical engineers processes, particularly in the capstone deign project subject) as well as in chemical product design.

The heat and mass transport processes covered in this subject include: diffusion/mass transfer, mass transfer with chemical reaction, mass transfer coupled with adsorption, conduction and radiation. The process will are applied to the design of separation unit operations including multi-component distillation, adsorption, solvent extraction, gas-liquid contactors with reactions. A number of problems in practical heat transfer scenarios involving condition and radiation are include as well.

The unit operations covered in the subject using the above processes include: Multicomponent and azeotropic distillation, including short cut and rigorous techniques for the prediction of column performance. Applications of liquid extraction, liquid-liquid equilibria; single-stage extraction, choice of solvent/feed ratio; continuous counter-current multistage extraction and the effect of axial dispersion. Adsorption and ion exchange - types of absorbents, fixed bed adsorber models, isothermal equilibrium and non-equilibrium design and operation. Application of mass transfer with reaction to equipment performance and design in gas-liquid contactors.

INDICATIVE CONTENT
