Basic criteria for choosing the right microstructured devices
Special Symposium - EPIC-1: European Process Intensification Conference - 1
EPIC-1: Poster Session (EPIC - Poster) - P2
Keywords: microreaction technology, microreactor, mixing quality
Microreaction technology and microchemical engineering are fast growing disciplines in chemistry and chemical engineering. A large number of microstructured devices with different mixing principles have been developed and microreactors have been used in a wide range of labscale applications for a lot of different reactions. [1, 2]
Microstructured devices provide a more efficient heat and mass transfer due to large specific surface areas. This leads to a higher yield and selectivity for chemical reactions. They use different principles with specific advantages and disadvantages. [3]
During our work in the field of microreaction technology we have generated a lot of experience with chemical reactions in labscale microreactors and the upscaling of these processes. In this work we present a set of criteria we found to be important in the process of choosing a microreactor for a given application. Usability, mixing quality, scalability and economic aspects are among the criteria that are discussed. Here we will mainly focus on liquid/liquid reactions. Some general guidelines reactor selection will be given and a few special cases like the mixing of liquids at different phase ratios and/or with different viscosity will be discussed.
