Course Schedule

This module provides students with a basic concept of chemical engineering processes and related problem‐solving methods. 

It provides a comprehensive introduction to the principles of chemical engineering process analysis. 

The module begins with an overview of the chemical process industry and a discussion of several significant examples. 

Details of steady state material and energy balance, including recycles, by‐pass, purge, phase change and chemical reaction, form the core substance of the course. 

Other topics include simultaneous mass and energy balances and unsteady state balances. 

All concepts and principles are amply illustrated with relevant process examples. 

This module is targeted at level one engineering or science undergraduate students. 

Aims and Objectives

9

On successful completion of this module, students will be able to:  Master general knowledge and fundamental concepts of chemical 

engineering principles;  Develop problem solving abilities for engineering design of chemical 

processes;  Analyze and handle steady state mass and energy balances using 

systematic approaches;  Design and integrate mass balances and energy balances for multiple 

chemical processes;  Differentiate and handle unsteady state mass and energy balances 

using approximation methods.
