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 http://www.services.unimelb.edu.au/disability/

This subject extends chemical engineering flowsheet calculations to include energy balances. The concept of conservation of energy is developed as the basis for determining energy flows in and around chemical processing systems, evaluation of enthalpy changes with and without phase change, simplified energy balances for batch, steady-state and adiabatic systems, estimation of heats of reaction, combustion, solution and dilution, energy balances in reacting systems, simultaneous material and energy balances. Performing computer-aided balances in the chemical engineering software package HYSYS is covered, as well as the use of Microsoft Excel in engineering calculations. Students are also taught concepts in process safety, with an emphasis on calculations related to fires and explosions. The subject will include exercises in process optimisation and the solution of ill-defined process problems.

On completion of this subject students should be able to

• Draw flowsheets for appropriate chemical engineering processes
• Calculate energy flows within such processes, including evaluation of enthalpy changes with and without phase change, simplified energy balances for batch, steady-state and adiabatic systems, estimation of heats of reaction, combustion, solution and dilution, energy balances in reacting systems, simultaneous material and energy balances
• Use chemical engineering software packages to perform energy balances
• Perform process optimisation and solve ill-defined process problems

• Four assignments spread throughout the semester, each of no more than 1500 words (10% each)
• One written two-hour end-of-semester examination (60%)
• A mark of 40% or more in the end of semester examination is required to pass the subject
