Further information on descriptions Description: Aims:
To introduce the principles and practices of:
* material and energy balancing, both steady state and unsteady state, for non-reacting and reacting systems in chemical and biochemical engineering,
* reaction engineering as applied to chemical and biological reactor design, and
* separation processes of relevance to the chemical engineering profession,
including how these subjects are integrated in process design and analysis.

Learning Outcomes:
After successfully completing this unit students should be able to:
* Formulate and solve manually material and energy balances for process systems that may include multi-component streams, phase changes, simple reactions, recycles, purges, by-passes and mixing;
* Perform simultaneous material and energy balances on adiabatic, non-adiabatic and isothermal reactors, including equilibrium-controlled reactions;
* Calculate reaction orders, rate constants and half-lives for simple reaction mechanisms;
* Apply the Arrhenius equation to calculate activation energies;
* Distinguish between various reactor types and explain their applications in chemical and biochemical processes;
* Outline the basic features of membrane processes, distillation processes, absorption processes and liquid /liquid extraction processes;
* Select appropriate membrane technologies for a particular separation problem;
* Understand the operation of single and multistage distillation columns;
* Design simple multistage binary distillation columns; and
* Carry out ternary multistage solvent extraction calculations.

Analysis and problem solving (taught/facilitated and assessed).
