Distillation System Design

Key Benefits

  • Sequencing of simple distillation columns

  • Understanding the benefits and degrees of freedom in dividing wall (partitioned) distillation columns
  • Heat integration of individual distillation columns
  • Heat pumping in distillation
  • Heat integration of distillation sequences
  • Introducing refinery distillation


This course provides the principles of distillation system design, emphasising energy efficiency. The course is aimed at process engineers who have some experience of conventional distillation and who wish to learn about advanced distillation system design.

Even though distillation is a well established and mature technology, there is still often considerable scope to improve the performance of distillation through the application of the latest integration techniques.

The sequencing of distillation columns and the appropriate use of complex distillation arrangements can bring remarkable reductions in energy costs and, in new design, reduction in capital costs also. The appropriate heat integration arrangements can also bring significant reductions in energy costs.

To obtain the best results requires the distillation sequence and heat recovery arrangement to be designed simultaneously. These techniques applied in retrofit situations can lead to reductions in energy cost, increases in throughput or a combination of both.

Who Should Be Trained?

The course is intended for people with a chemical engineering background working in the petroleum, petrochemical or chemical process industries, or in engineering and consultancy companies servicing those industries. Process engineers with an interest in making distillation operations more efficient should attend this course.
