Core Participation Requirements:

For the purposes of considering applications for Reasonable Adjustments under the Disability Standards for Education (Cwth 2005) and Students Experiencing Academic Disadvantage Policy, this subject requires all students to actively and safely participate in laboratory activities. Students who feel their disability may impact upon their participation are encouraged to discuss this with the Subject Co-ordinator and the Disability Liaison Unit



Subject Overview:


This subject is an introduction to chemical engineering flowsheet calculations, including materials balances, unit systems, and the prediction of real gas behaviour. The concept of conversion of mass is developed as the basis for determining mass flows in chemical processing systems. Students will be introduced to flowsheeting packages and chemical engineering simulation software. The subject will include exercises in process optimisation and the solution of ill-defined process problems.

This subject together with CHEM20008 Chemical Process Analysis 2 provides the basis for all the chemical engineering subjects that follow. The calculations introduced in these subjects are the most common type of calculations performed by professional chemical engineers working in all sectors of industry.

The teaching of process safety is critical to any undergraduate chemical engineering program. Students need to understand their responsibilities to themselves, their work colleagues and the wider community. They need to be aware of safe practices and also the consequences that may arise when those safe practices are not followed. This subject introduces students to concepts of process safety and the consequences when safety management systems fail.


Topics covered include material balances around single process units and groups of units, involving simple systems and recycle streams, and non-reacting and reacting systems. Total, component, and elemental balances are covered. Other topics include systems of units and unit conversion, gases, liquids and vapours, P-V-T diagrams of pure substances, ideal and real gas behaviour, use of compressibility factor and generalized compressibility factor charts, equations of state, vapour pressure estimation and humidity.

Learning Outcomes:


On completion of this subject the student is expected to:

  1. Apply knowledge of basic science and engineering fundamentals to solve material balances.
  2. Define and scope engineering problems and formulate suitable strategies for problem solution.
  3. Use appropriate software tools to solve material balances.
  4. Model real gas behaviour.
  5. Have developed an appreciation for the importance of safety in the process industries.
  6. Be able to continue study in the area of energy balances with a solid foundation.

  • Four assignments spread throughout the semester, each of no more than 750 words (10% each). Two of these assignments are associated with the laboratory experiments.
  • One written two hour end-of semester examination (60%).

Hurdle requirement: A pass in the end of semester examination is required to pass the subject.

Intended Learning Outcomes (ILOs) 1 to 4 and 6 are addressed in the examination and three of the four assignments.

ILO 5 is addressed in one of the assignments.

The examination paper will consist of problems designed to test whether the student has acquired the ability to apply fundamental principles to the solutions of problems involving material balances and real gas behaviour. The problems set for the exam will be similar to those undertaken in the tutorial classes.
