A group project, where students have the opportunity to go through all the steps of designing a process plant including feedstock and process selections, mass and energy balances, control strategy, project economics, process safety, environmental impact, and community engagement.

This course provides students with a close to real world experience of process engineering.  It is built around a major design project where students have the opportunity to go through all the steps of a real design project as outlined in the learning outcomes below.  The major project also provides the experience of working in groups, an important skill for life after university.  

Students work in groups of four (or three) on their design projects during semester 2.  Each group must produce an executive report and hand in their working folders at the completion of each major section of the design. There are three reports: two during the semester and the final report is due in late October (more details below).  Students will make 3 presentations to their design supervisors during the course of their project (one in the third term and two in the fourth term and exam period). They will be group presentations where all the students in a design group will be given the same mark.  There will be two formal group presentations as you might give to an external customer and one informal, round table style presentation as you might give to your boss at a consultancy.  In the final individually written assessment, each student will describe their personal contribution to the design project and will be awarded an individual mark. The project report mark will be biased by peer- and supervisor-assessment of an individual student’s contribution to the group effort. The basis for the peer assessment will be explained in tutorials.

Learning Outcomes

  • To apply the design process in a team environment to a real chemical engineering project including:

  • Determining the best choice of process
  • Creating a process flow diagram
  • Quantifying material and energy balances
  • Creating a control strategy
  • Creating a detailed design of a select unit operation
  • Creating a piping and instrumentation diagram for a select unit operation
  • Evaluating the economics of the project
  • HazOp assessment of a major unit operation
  • Evaluating the impact the process will have on the surrounding community


a pass in all compulsory Second Professional Year courses, ENCH496 and ENCH497

Timetable Note

Major project report and presentations and safety assessment case.  Students should expect to work for 20 hours a week during semester 2 on their major design project.
