Heat pipe

Distillation System

Codename: #teamDS

After the CO2 and hydrogen mixture through the Methanol Synthesis part, a mixture of methanol and water remains. This liquid-liquid mixture needs to be separated using for instance distillation. Using a conventional distillation column would have a negative effect on the energy balance and investment cost of the system. Therefore other ways of separating the methanol water mixture are considered. In literature a micro-distillation concept is described based on the principle of the heat pipe. A heat pipe is a device in which a condensable vapor flows from a hot surface to a cold surface where it becomes a liquid that then travels in the opposite direction by capillary action or gravity. [Seok et al]

Furthermore, in the paper by Seok et al, an experimental setup is described which can be used to validate the working principle of this distillation column. This system seems suitable to use for the separation of the methanol water mixture.

Approach

Process modeling (calculate stuff)

  • Heat and mass transfer in column based on theory in Seok and other sources
  • Make an equivalent PFD with a conventional column in order to validate the models
  • Dynamic model (matlab)

Component design (draw stuff)

  • Make a 3D CAD model of the heat pipe
  • FEM analysis of the heat pipe
  • Manufacturing plan
  • Talk to suppliers / manufacturers / industrial design experts

Experimenting / Testing (build stuff)

  • Component building
  • Yield testing
  • Manufacturability: talk to suppliers / manufacturers / Industrial design experts
  • Temperature test
  • Pressure test
  • Max flow test
  • Run the same experiments as Seok et al Figure 3.
  • Use the panel to test the performance of certain subsystems.
