Stirring tank reactor vs. microreactor

Readingtime 1 minutes

When chemicals react with each other, heat is often generated and has to be dissipated. Small flow tanks, which are manufactured using 3D printing, enable more efficient cooling than classic stirred tanks. A comparison of the two systems

STIRRED-TANK REACTOR
The large reactor volume generates a lot of heat. A very cold coolant (nitrogen at -196°C) has to be pumped through the reactor casing to ensure that no part of the tank gets too hot.

Microreactor

Stirred-tank reactor

☐ = Ø annual electricity consumption of 100 German households: 310

Microreactor

Stirred-tank reactor

☐ = CO2 emissions of an Airbus A320 on a flight from Munich to Berlin: 37

*Relative to the cooling requirement for a production volume of 150,000 tons per year for ortho-lithiation
MICROREACTOR
Many thin reactor tubes ensure that the local temperature stays lower. Because all the tubes are surrounded by a cooling medium, the heat is also better dissipated.
New production process
3D printing enables reactor components to be manufactured in shapes that would be very expensive to make using conventional production processes such as injection molding.

Chemical Production

A reactor with a good energy balance

Researchers in the ROMEO project have developed a process that makes an industrial reaction more energy-efficient.

Climate Change

More efficiency for climate protection

Despite many setbacks, an increase in energy efficiency is still the most viable way to limit the effects of global warming.
