1 day

Develop a fundamental understanding of gas fluid separation and gas absorption engineering by solving problems through reasoning.

Gas-fluid separation based on absorption and distillation

Absorption is a mass-transfer process in which a vapor solute in a gas mixture is absorbed by means of a liquid in which the solute is more or less soluble. The gas mixture consists mainly of an inert gas and the solute. The liquid also is primarily immiscible in the gas phase; that is, its vaporization into the gas phase is relatively slight. Subsequently, the solute is recovered from the solution by distillation. In the reverse process of desorption or stripping, the same principles and equations hold.

The goal of this course is to develop a fundamental understanding of gas fluid separation and gas absorption engineering. This will be achieved by solving gas fluid (liquid) separation and gas absorption engineering problems trough reasoning.

On completion of this course you are able to:

  • Calculate flows and composition in single and multiple equilibrium contact stages by using both an equilibrium relationship and a material balance
  • Use analytical and graphical techniques to calculate the number of stages needed for either an absorber / stripper
  • State the differences between loading point and flooding point in a packed column
  • Compare the three different types of trays based on efficiency and design
  • Calculate, for a packed column, the height equivalent to a theoretical plate/stage; then, explain its difference from the height of a transfer unit
  • Calculate, for a packed column, the number of theoretical plates/stages; then, explain its difference from the number of transfer units
  • Plot an x, y diagram using Raoult’s law, Distinguish between a minimum and a maximum boiling azeotrope
  • Describe the three common types of column internals used in a distillation tower
  • Describe the differences between batch and fractional distillation
  • Use the McCabe–Thiele method to solve a variety of binary distillation problems
  • Describe and calculate the three types of tray efficiencies
  • Use shortcut methods for multicomponent distillation to calculate number /optimal feed stages

Using influences of the distillation process for process optimization

During the course:

  • You get an overview of different gas fluid (liquid) separation and gas absorption mechanisms
  • A divers series of distillation types and gas absorption types is treated
  • Optimalization of separation and distillation and gas absorption types is allocated
  • The newest developments on distillation / separator and gas absorption design and application will be dealt with
  • You learn to understand the influence of a good distillation process design on the products and the separation
  • You learn what the important factors are that influence the process
  • You get an overview of available types of separation processes
  • You learn how to optimize existing processes

Intended for
The course is meant for engineers, technologists, designers with a chemical, process, technological or mechanical background on bachelor or master level.

Within the program you can take six other courses. View them all on the page Chemical Engineering.
