The subject

What Distillation covers

This course equips learners to design, troubleshoot and optimise a wide range of distillation columns using a combination of theoretical and industrial principles. It gives a detailed overview of column types from binary to multi-component, reactive and pressure-swing systems, and explores ideal and non-ideal VLE systems in detail to explain the working principles of each type of operation. The McCabe-Thiele, Modi & Westerberg and Ponchon-Savarit methods are used to design different columns using the techniques unique to each, considering bubble and dew points and isolating the rectifying and stripping sections. Additional content covers sequencing and heat integration, including forward and backward integration methods. Learners come away able to understand the various column types and their pros and cons; design and model binary and multi-component columns; apply the McCabe-Thiele method graphically; apply the Modi & Westerberg shortcut method; use the Ponchon-Savarit method; and use sequencing for integration and optimisation.

What you’ll be able to do

  • Explain why distillation is efficient for separating liquid mixtures
  • Explain why multi-component systems rather than binary systems are used in industry
  • Define an azeotrope by matching vapour and liquid compositions
  • Apply a mass balance to differential distillation of a binary mixture
  • Locate the rectifying section above the feed point in a column
  • Define distillation sequencing as the order of product separation
