CHE2113, CHE2140


This unit will introduce students to the fundamentals of material and energy balances through a systematic treatment of: single and multiple unit operations, reactive and non-reactive processes, recycle and bypass, extent of reactions, equations of state, vapour-liquid phase equilibrium, solid-liquid phase equilibrium, internal energy and enthalpy changes for process fluids undergoing specified changes in temperature, pressure, phase, reactions and chemical compositions and computer aided simulation of process flow diagrams. A process simulation software will be used to aid in the solution of more complex systems.


At the successful completion of this unit you will be able to:

  1. Apply the basic concepts of conservation of mass and energy, including phase equilibrium, reaction equilibrium and non-ideal gas behaviour to mass and energy balances.
  2. Apply the concepts of unit operations to combine them into a block flow diagram and process flow diagram of a chemical process.
  3. Interpret physical property charts and diagrams to solve problems based on phase equilibrium, refrigeration and heat pump cycles.
  4. Analyse the mass and energy balances of any chemical process, for both steady and unsteady state situations.
  5. Simulate processes using a process simulation software to analyse the mass and energy balance of complex chemical processes and report the results in a technical report.
  6. Interpret experimental measurements of mass, energy and chemical composition and report the results in a lab report.


Laboratory/Assignments/Test: 40% + Examination (2 hours): 60%

Students are required to achieve at least 45% in the total continuous assessment component (assignments, tests, mid-semester exams, laboratory reports) and at least 45% in the final examination component and an overall mark of 50% to achieve a pass grade in the unit. Students failing to achieve this requirement will be given a maximum of 45% in the unit.

Workload requirements

6 hours of contact time per week, which includes lectures, practical classes and computer labs; 6 hours of private study per week and one 4-hour lab during semester.
