This online course covers essential distillation concepts likely to be faced by process support, operations, and process design engineering personnel. Along with a review of vapor liquid equilibrium, this course covers process design, column operation and simulation issues. In addition, you will also learn about specification and selection of the appropriate distillation hardware. 

Learning Outcomes:

  • Discuss essential distillation fundamentals such as vapor liquid equilibrium, stages, and transfer units.
  • Describe a variety of distillation practice designs including general column design, tray column design, packed column design.
  • Employ basic troubleshooting techniques.
  • Discuss the current methods for estimating efficiency.

Who Should Attend:

Engineers or others who must troubleshoot and solve difficult distillation problems in the plant, or conceptualize difficult distillation problems in the engineering office or laboratory. Ideal for both veterans and those with only a few years’ experience, the course addresses essential distillation concepts and is especially beneficial to process support, operations, and process design engineers.
