Microreaction technology

from Wikipedia, the free encyclopedia

Micro reaction technology is a new technology for the extremely scaled-down construction of process engineering plants .

The micro-reaction technology (MRT) enables the secure development of chemical processes and the development of safer and more efficient production. The main components built up in microstructures are mixers with an extremely good mixing effect and heat exchangers with extremely good heat transfer . There are also miniaturized reactors , filters , heating modules, sensors , valves , pumps, etc.

Advantages of the continuous operation in microstructures are

  • ultra fast mixing,
  • more effective heat transfer ,
  • better mass transport in reactions with a solid catalyst ,
  • short controllable dwell times ,
  • optimal controllability through low system inertia and
  • high operational safety due to minimal content.

Typical basic procedural operations that are carried out with micro-reaction modules are:

Micromodules can also be integrated into conventional process engineering systems.

With the help of micro-reaction technology, complex or critical reactions can be precisely controlled, thus increasing the safety of chemical production. In addition, the systems can be built smaller, implemented with lower investment and operated more efficiently. A particular advantage is the high specific surface area of the micromodules, which results in the very good heat and mass transport properties.

In microreaction technology, the step from development to production is carried out by so-called numbering-up instead of complex scale-up . Numbering-up means increasing the throughput by connecting up to ten lines in parallel. The scale-up can be implemented in a mini- plant analogous to classical process engineering . This is then referred to as the flow miniplant .

Micromodules are used economically, for example, in the screening of drugs , since a large number of different substances can be produced and tested simultaneously in a small space.

One type of microreactor is the photomicroreactor .
