This is one of key courses in chemical engineering which covers methods for the quantitative analysis of chemical and process modelling and applications, unit operation and overall process mass and energy balances, optimisation, heat exchanger design, and sustainability assessment. It also includes guidelines for society and cultural implications of process decisions and how to engage with iwi and local communities, and some practical and effective guidelines on how to do this.

The following topics are taught in this course:
Process Modelling (12L, Daniel)
- types of models
- dynamic modelling of processes
- solution methods

Heat Exchanger Design (6L, Heon)
- design shell-tube heat exchanger
- design plate heat exchanger
- economic analysis

Optimisation (4L, Heon)
- object function, degree of freedom, global/local optimum,
- modelling, curve fitting and optimisation using Excel
- algorithms (genetic, Monte Carlo, Dijkstra, travelling salesman, discrete)
- case study: ethanol production

Sustainability (8L, Heon)
- how to calculate carbon foot print
- life cycle assessment
- quantitative measure of sustainability and metrics
- environment-related legislation, carbon neutral, emission trading, international agreements

Biculturalism (3 visits, Carlo):  Three on-site workshops (2 hours each)
- how indigenous identity and historical narratives are being woven into the new Ōtautahi Christchurch streetscape.
- introduction to Māori social structures, values, tūrangawaewae, mihi development and tikanga Māori;
- how, as engineers, students should go about engaging with mana whenua and stakeholders

Learning Outcomes

Timetable Note

30 lectures and 3 local visits

Students are expected to attend all lectures or to study Echo360 videos if attendance is not possible, spend 6 hours per week reviewing lecture contents, studying textbooks and references, making own notes, and preparing for labs. Students are also expected to spend about 1 hour per assignment mark.

Students should consider mid-semester break as catching up time, not holidays. Thus, this period should be utilised for reviewing, previewing, and preparing for assessments.

In addition to 30 regular lectures, the bicultural section will be taught by guest lecturers with visiting Māori engineering engagement experts. The day-long marae visit will involve lectures and discussions sessions primarily run by local iwi, Beca, with assistance from our AVC Māori.
