This course focuses on applications of transport processes in separation processes.

Applications of transport processes in all separation processes in chemical engineering

During all separation processes components want to move to the lowest concentration or temperature. Also during reactions components need to migrate to each other to make a the reaction possible. Mass or heat transfer occurs when a component in a mixture migrates in the same phase or to another phase due to a difference in concentration or temperature between two points.

A practical approach: effect of mass, density and temperature on mass, heat transfer and flow. Flux is about transfer related to velocity, temperature or concentration when they are not constant, quantity of a property passing through per unit area per unit of time. It is often proportional to the gradient of another property. The modes of heat transfer are conductive heat transfer (conduction), convective heat transfer (convection) and radiative heat transfer (radiation).

Pumps give energy to the fluid, to transfer it and transform mechanical energy (rotation of the impeller of the pump) to fluid energy so they use kinetic energy to make potential energy. There are two types of pumps: centrifugal pumps and volumetric pumps, with their own working behaviour. Thus behavior depends on the working point of the pump as cut of pumpcurve and systemcurve. The flow control is by means of frequency, rpm or valve.

Insight into physical transfer phenomena and heat transfer

After completing this course you are able to:

  • Perform a simple mass balance on a fluid process
  • Explain the difference between a fluidized and a packed bed
  • Explain the differences between particulate and bubbling fluidization
  • Calculate the minimum fluidization velocity for a fluidized bed
  • Apply the energy balance to the design of a pump
  • Extend the overall energy balance to derive the overall mechanical energy balance
  • Explain how the concept of work and energy is applied to pumps and piping systems
  • Calculate the energy needed to operate a pump in a piping system
  • Recognize that a temperature difference is the driving potential for heat transfer
  • Know the difference between a heat flux and a heat rate
  • Realize that heat transfer may occur by one of the three basic mechanisms of heat transfer: conduction, convection, and radiation
  • Solve problems in which heat is transferred by conduction in different materials/fluids in series or in parallel

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