Laboratory and pilot-plant experiments, design and analysis of experiments using statistical methods, and computational tools useful for analysing data.

Learning Outcomes

  • Practical demonstration of hardware, concepts and phenomena in relation to the broader context of a process engineering system.
  • Solve open ended chemical engineering problems by researching, designing, planning and conducting experiments.
  • Gather, manage, interpret and use experimental information appropriately.
  • Effective communication using a variety of formats to a variety of audiences.
  • Function effectively in a team environment by working cooperatively with your lab partner.


Timetable Note

• 6 experiments with process equipment at pilot plant scale, reported in various ways.
• 18 lectures.

Course Coordinator / Lecturer

Carlo Carere

Lab Coordinator

Alfred Herritsch

During the course you and your lab partner will do 5 experiments with all reports being written individually. All lab reports must be submitted to complete the course. 50% of your grade will be deducted for a late submission.


Laboratory Dress Code
Proper dress, footwear and protective equipment are demanded in the laboratory at all times - open sandals and jandals are not permitted and long hair must be restrained. Lab coat and safety glasses must be worn at all times.

No Food or Drink
You are not allowed to eat and drink inside the laboratory and will not be permitted into the lab if you have imbibed alcohol in the previous 4 hours (including during ENSOC socials!).

Sign In and Out
It is important that you sign yourself onto the lab roll when coming into the lab, and sign out whenever leaving the lab, so that an accurate list can be kept at all times in case of this emergency.

Be Considerate
Students are urged to be considerate to their lab partner and demonstrator by warning them as far as possible in advance of sickness or other reason for not coming to the lab session. We will try to be flexible in such circumstances, but if it is evident that there is no good reason for absence, you will be at risk of missing the lab, and so failing the unit! Also keep your cool if things don't go as expected! That is all part of experimental work and developing professional patience.

In an Emergency
If the laboratory is evacuated for an emergency, all students must shut down their experiment, if it is safe to do, and leave the building immediately to gather on the grassy area at the corner between Forestry road and Creyke road, to be counted so that complete evacuation of the building can be checked.


Assessment Due Date Percentage  Description
Formal Report 35% A longer and more in depth analysis of the results. In addition, students will supplement this with the data from other students who have completed the lab in the same year. This will result in an augmented statistical analysis, which may result in suggestions for lab improvements. Final report to be submitted 4 weeks after the experiment.
Management Report 1 20% Reports to management (due 1 week after the lab)
Management Report 2 20% Reports to management (due 1 week after the lab)
Short Formal Report 1 10% A rapidly-executed industrial report to immediate superior. The report is due on the same day that the lab is completed.
Short Formal Report 2 10% A rapidly-executed industrial report to immediate superior. The report is due on the same day that the lab is completed.
Workshop 5% A lab on P&IDs of CAPE's distillation column (approx 2 hours).

Textbooks / Resources

Required Texts

Montgomery, Douglas C; Design and analysis of experiments ; Eighth edition; John Wiley & Sons, Inc., 2013.

Recommended Reading

Montgomery, Douglas C. , Runger, George C; Applied statistics and probability for engineers ; Sixth edition; John Wiley and Sons, Inc., 2014.


Scheduled as described in “My Timetable”

Laboratories run during mornings, see MyTimetable for details. Students will be grouped in Term 1.  Each group will complete the following experiments:
• LabA: P&ID drawing
• LabB: Heat Exchanger - Plate heat-exchanger - heat balances and heat transfer coefficients
• LabC: Spray Drier – Material and energy balances to determine drying rates for scale-up
• LabD: Reactor – Batch stirred tank reactor to determine kinetics of conversion of vegetable oils into biodiesel
• LabE: Filtration - Lab-scale investigation of membrane separations
• LabF: Distillation experiment - Practical experience with a large pilot-scale continuous distillation column

• 6 laboratory days with contact time 3-6 hours each, time of report preparation 10-25 hours for different report styles, total 130 hours
• Lecture attendance (approximately 15 hours)

This course builds on the skills acquired in first-professional year chemical engineering laboratories, extending the range of reporting, allowing the student to take more initiative, and generally increasing the size of the plant used to pilot scale. The experiments are related to other ENCH 300 series courses currently being studied.

Additional Course Outline Information


Must attend all labs.

Late submission of work

50% of grade for late submission.

Other specific requirements

The following information is valid for all laboratory days and should be read carefully!

Laboratory Preparation
Before each laboratory class, each pair must see their demonstrator and must individually hand in (please arrange meeting at least 5 working days in advance):

• a completed sample calculation with an adequate line diagram of the equipment.
• a completed safety-check sheet (available on Learn)
• any proposal required.

These are marked for “lab preparation”. Help may be obtained from the demonstrator and your tutor for that experiment. The penalty for not completing these may be zero marks for “preparation”. Note, this is worth 20% of the total marks for the improvement labs! The onus will be on the students to find the demonstrator and tutor before the Monday hand-in of preparatory material.

General Comments
• For all written reports, please email the spreadsheet used to your demonstrator.
• All reports must have an error analysis leading to error bars on the main result graph, based on either replication or error propagation (the formal report has both).
• All reports must use SI units.
• All reports must have a flow diagram (Visio is available). Use drawing symbols as in Coulson and Richardson, vol.6, Appendix A.
• To reduce paper, reports can be printed on both sides of the page, except the title page.
• It is recommended that an A4 exercise book is used to write lab observations in for all experiments. Photocopy the page(s) to attach as an appendix to the relevant report. The appendix and spreadsheet must be able to be understood independently – label and explain the spreadsheet working, within the spreadsheet.

Demonstrators’ Availability
The demonstrator will start you off on the laboratory at the agreed time then will be available during the morning at some location within the department, and will return before 12 pm to check on any difficulties. There will always be a demonstrator on duty present at all times during the lab sessions you can refer to if you need help.

Laboratory Briefing Sheets
These are available for viewing and printing on Learn.

Report Templates
Report templates are available on Learn and contain information on content, report structure and penalties.

Where to submit and collect work

Reports need to be submitted electronically via Learn and a hardcopy should be handed in the box “ENCH395 CAPE Labs” at the entrance to the CAPE department level 4 LINK Building. If you wish to extend the deadline for handing in your lab report and have a good reason contact or see Alfred Herritsch.
