NEPUMUC

New Eco-efficient Industrial Process Using Microstructured Unit Components.

Executive Summary

The overall goal of the NEPUMUC project was to investigate strategies for making the benefits of microreaction technology available for industrial purposes, in particular for nitration processes in chemical industry.

Therefore, the project partners have jointly developed, tested and evaluated a new microreaction process for nitration reactions as a prototype to investigate how microreaction technology can be made available in a flexible and multi-purpose manner under industrial requirements.

The project has addressed different technological challenges by new and innovative methods and process technologies. For the first time, simulation and modelling tools were consequently applied for the design of both the entire nitration process and its core component, the microfluidic reaction unit. This is a new approach since it translates the requirements of specific chemical reactions into a microfluidic process design to achieve best performance under sufficient throughput.

To enable a robust, stable and safe processing under industrial requirements, new microfluidic sensors have been developed and adapted to the microreactor unit which was made of glass. These sensors allow an accurate process monitoring and process control in the immediate vicinity of the most important part of the process: the microreactor. For the first time, microfluidic sensors became an integral part of a microreaction process designed on basis of industrial requirements.

Finally, an appropriate autom ation system has been developed that interacts accurately with both microfluidic sensors and macroscopic actuators (pumps, heating/cooling devices, etc.) to make microreaction technology processable like conventional chemical processes in industry.
The technological developments in the project were supported by an evaluation procedure to investigate the technical and economic benefits but also the potential limitations of the microreaction process. For this purpose, the entire chemical process has been considered comprising the microreaction unit but also the subsequent downstream processing (e.g. separation and cleaning procedures).
