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.
