Chemical engineering separation operations including humidification/dehumidification, drying, membrane separations, leaching and washing, crystallisation, ion exchange, distillation, gas absorption and liquid-liquid extraction.

This course covers process operations involving separations. The fundamental mass and energy transfer theories will be discussed in the context of: drying, (de-)humidification, membranes, leaching/washing, crystallization, ion exchange, distillation, gas absorption, and liquid-liquid extraction.

Learning Outcomes

  • At the end of the course the students are expected to be able to:

  • Understand the value and context of separation processes.
  • Understand the fundamental phenomena utilized in separation processes.
  • Develop skills for identifying the key separation problem and developing effective solutions.
  • Understand and analyse specific separation processes including distillation, gas absorption etc.
  • Select appropriate separation techniques for chemical processing.
  • Relate fundamental separation phenomena to equipment design and operation.
  • Carry out design calculations for separation processes.

Course policy on collaboration and cheating:
Solving problems in small teams and collaborative learning when working on assignments is encouraged.  However direct copying will result is reduced or zero marks for all students involved.

The assignments are mainly a tool to prepare you for the exams. We advise you to try them individually before collaborating in groups.

Students with concerns about the course should contact any of the lecturers listed above, the 3rd Year Director of Studies (Dr. Carlo Carere), or the Head of Department (Prof. Peter Gostomski).

General Policies of the University
Students may obtain the general policies of the University from the website.  For example:

Special considerations: http://www.canterbury.ac.nz/study/special-consideration/  

Academic Appeals of Assessments: Students with concerns about assessment processes or grades should be advised to speak first with the relevant lecturer. If the matter cannot be resolved, then the student should meet and discuss the matter with the Head of Department/School and thereafter follow the procedures outlined in the University procedures https://www.canterbury.ac.nz/media/uc-policy-library/general/Academic-Appeals-and-Grievances-Principles-and-Procedures.pdf  and regulations https://www.canterbury.ac.nz/media/documents/regulations/general-regs-academic-appeals-and-grievance.pdf

Reconsideration of grades: If you are concerned that your final grade may be incorrect it is suggested (for CAPE) that you make an informal query to the course coordinator, but you may follow the official procedures: http://www.canterbury.ac.nz/study/examinations/result-dates-and-appeals/

Disabilities: http://www.canterbury.ac.nz/disability/

This is a compulsory course which provides a basis for many other courses in chemical engineering.
Prerequisites: ENCH292.
