Heat Exchange: Mix-Reaction


The MR heat exchanger geometry consists of a structure of crossing, intermeshing pipes which are installed into the flow channel and simultaneously mix, cool or heat the highly viscous product. The tubes will be flushed by the service fluid (mostly thermal oil, water or steam) from a chamber. The product flows through these bundles. The flow is continuously split, stretched, recombined and conveyed.

  • Tube bundles are both mixing elements and active heat transfer surfaces, therefore high heat transfer coefficients 4-10 times higher than in an empty pipe.
  • High heat transfer capacities with single flow channel – no maldistribution.
  • High degree of plug flow, therefore uniform time, temperature and shear history.
  • Very low pressure drop
  • 100 % scale-up capability (scale-up of test data is accurate, ratio 1:100)
  • Large process side volumetric heat transfer area of 90 – 150 m2 area /m3 heat exchange.
