“…For the use of reactors in transformable production plants, the focus lies mainly on continuously operated equipment solutions, which include several basic operations (reaction, heat transfer). The developments of recent years show that especially micro current reactors are found to be suitable due to improved mixing and heat transfer, less potential hazards, and better controllable residence times .…”

The process industry faces the challenges of intensified, global competition with increasing market dynamics. Modular, transformable production concepts promise a better adaption to these in the dimensions of throughput, product mix, and production location. In order to unfold the full potential, modularization and transformability have to be carried out not only on the plant and logistics level, but also on the apparatus level. Characteristics like setup and scaling concepts are discussed. Examples for modular apparatuses concerning the process engineering tasks of mixing, heat exchange, reaction and separation are presented and further research needs are derived.

“…Krasberg et al proposed a computer-aided methodology for conceptual design and scale-up of modular continuous processes using the container technology available at the INVITE facility at Bayer Company [8]. In essence, given the process data are known, the methodology enables the selection of the appropriate reactor unit for homogenous liquid phase reactions among various proposed operating alternatives.…”

Reaction-oriented research in flow chemistry and microreactor has been extensively focused upon in special journal issues and books. On a process level, this resembled the "drop-in" (retrofit) concept with the microreactor replacing a conventional (batch) reactor. Meanwhile, with the introduction of the mobile, compact, modular container technology, the focus is more on the process side, including also providing an end-to-end vision of intensified process design. Exactly this is the focus of the current special issue "Design and Engineering of Microreactor and Smart-Scaled Flow Processes" of the journal "Processes". This special issue comprises three review papers, five research articles and two communications.Rahman and Rebrov have presented an overview of the application of microreactors in the synthesis of gold nanoparticles (GNP) [1]. Considering that reactant mixing is one of the most critical factors influencing the GNP synthesis, batch operating conditions commonly pose great limitations to both quality and scalability of the process. In contrast, synthesis in microflow overcomes this constraint and allows to individually affect the diverse elemental steps within GNP synthesis, which provides unique chances in process optimization.Choi et al. have given the state-of-the-art of the microreactor-assisted solution deposition (MASD) technique for fabricating compound semiconductors, as well as instructive insights in scaling-up the MASD process by implementing the numbering-up strategy [2]. Special focus has been given on the application of the MASD in cadmium sulfide (CdS) thin film deposition. The MASD process exhibits advantages over the conventional batch chemical solution method by enabling operation at lower temperature, enhancing reaction selectivity, reducing capital cost and providing perspectives for process scale-up.

For complete chemical processes, downstream operation steps are essential, but on a miniaturized scale, they are not so far developed as the microreactors. This contribution presents three different unit operations for phase and component separation. Liquid-liquid extraction is often performed in columns, which were miniaturized for higher separation efficiency and flow rates suitable for processes in flow chemistry. Two-phase mass transfer processes in capillaries benefit from rapid final phase separation, which can be performed in an in-line phase splitter based on different surface wetting behavior. Crystallization is often a final purification step, which is performed in a continuously operated helical tube setup with narrow residence time distribution. For all unit operations, design criteria are shown with typical applications. The methodology of downscaling of known equipment and employing typical microscale phenomena such as good flow control, laminar flow, or dominant surface forces leads to successful equipment design.
