Investigation on the Synthesis of PCC Nanostructures using a Spinning Disk Reactor: Effects of Disk Speed

Application of process intensification technique in chemical-based synthesis processes has been a growing trend. In this regard, Spinning Disk Reactors (SDR) have attracted considerable attention due to their enhanced heat and mass transfer properties. Moreover, equipment’s inherent simplicity in changing the process parameters is considered to provide the user with the flexibility in fine tuning the nature and quality of products formed. In this study the effect on the particle size due to the changing rotational speed of the disk is discussed in relevance to the synthesis of Precipitated Calcium Carbonate (PCC) nanostructures. Hence, PCC has been synthesized in a locally fabricated SDR with a 15 cm diameter disk at different disk rotation speeds. The potential of the equipment to reduce particle size and further synthesize PCC nanostructures is identified. The obtained results are discussed in comparison to chemical kinetic data of previous studies.
