Paper Description

Edit Paper Description Content
The course will begin with the development of basic principles of mixing and fluid-phase equilibria theory, and will then move on to show how these principles may be applied to specific unit operations including, flash separation, binary and multi-component distillation, evaporation, drying and membrane separations. ENGCB280 and ENGCB224 should be completed before enrolling in this paper.

The course will be taught in the first semester, commencing with the first lecture on Monday, 25th of February.

Labs/Tutorials/Project Work

Laboratory work consists of three physical laboratory sessions in the first half of the term as well as computer lab sessions in the second half of the terms. Your lab reports, worth 10 % of the overall grade, should be submitted by 5pm of the Thursday following the lab. In addition, there will be a small project to complete. The report for this project will contribute 10% to the final grade. A tutorial will be held most weeks and assignments set in these tutorials will contribute 10% to the final grade.


There will be one test in addition to the end of semester exam. The test will contribute 20% to the final mark. The test date is Wednesday April 14th 2021.

Important Note for International Students: For international students in New Zealand under student visas, regular attendance is part of your visa obligation and is checked as a requirement on the University under the Code of Practice for the Pastoral Care of International Students, to which the University is a signatory. Academic staff are formally required to monitor attendance in classes and submission of compulsory assessment events/items and to report to Waikato International in the event that any problem with irregular attendance or non-submission is not resolved.
