Novel Mesoscale Segmented Flow Reactor
Dr Arran Solomonsz, Technical Manager at Asynt commented “We were delighted to be chosen by the University of Bath as a collaborative partner in the development of their mesoscale segmented flow reactor and the results of the initial evaluation experiments carried out on the system look very exciting”. He added “As well as designing the mesoscale reactor framework exterior, Asynt were involved in the design and supply of robust, high performance heating technology for feed vessels, custom manufactured meso coil reactor heaters, detailed specification of the required pumps as well as flexible tubing jackets to maintain the temperature within these conduits”.
Dr Karen Robertson of the University of Bath said “We chose to work with Asynt because of their extensive experience of designing specialist reactor systems and expertise in heating block technology. Throughout the development and experimental trials we have been very happy with the technical knowledge, design ideas and overall support provided by Asynt”.
The University of Bath mesoscale flow reactor has been demonstrated to be capable of processing precipitation reactions and crystallizations. The modular nature of the system, range of configurations possible and independent control over feed solutions results in a highly versatile platform. A wide range of crystallizations or reactions can be performed using this apparatus with a high degree of kinetic control. The use of liquid-segmented flow in the system enables plug flow to be generated and mitigates encrustation while providing a sterile environment in which primary nucleation can occur free of external stimulus. As a result nucleation is induced in a consistent and reproducible manner, a critical advantage in delivering selectivity and consistency in the solid form particles produced. The design of the system which provides separation of the carrier fluid prior to filtration, without impact on the precipitate, enables continuous use of this crystallizer. The small scale of the system makes it ideal for research laboratories and the production of high value and rare chemicals.
