Continuous Reactive Crystallization in a Mesoscale Oscillatory Baffled Reactor

Chemical Engineering & Technology, 2023
AbstractContinuous reactive crystallization was carried out in a mesoscale oscillatory baffled reactor (meso‐OBR), using calcium carbonate as a case study to demonstrate the ability of high solid loadings and to examine the fouling potential in continuous processes. Plug flow behavior was easily achieved in reactive solid‐liquid phase reaction systems,

Continuous flow synthesis of zeolite FAU in an oscillatory baffled reactor [PDF]

Journal of Advanced Manufacturing and Processing, 2020
AbstractIn this work, we report, for the first time, the continuous flow synthesis of zeolite NaX successfully accomplished in a pilot‐scale (up to 100 L/h) continuous oscillatory baffled reactor (COBR). The continuous synthesis was achieved by combining the seed‐assisted method, in‐line mixing of reactants at high temperature and COBR.

Mass transfer enhancement as a function of oscillatory baffled reactor design [PDF]

Chemical Engineering and Processing - Process Intensification, 2018
Abstract Air-water two-phase flow regimes were identified quantitatively and qualitatively for four designs of oscillatory baffled reactor (OBR) over a range of oscillation conditions in semi-batch mode operation (continuous gas phase; batch liquid phase). The baffle designs assessed were helical baffles, smooth periodic constrictions, single orifice

The Hydrodynamics and Mixing Performance in a Moving Baffle Oscillatory Baffled Reactor through Computational Fluid Dynamics (CFD) [PDF]

Processes, 2020
Oscillatory baffled reactors (OBRs) have attracted much attention from researchers and industries alike due to their proven advantages in mixing, scale-up, and cost-effectiveness over conventional stirred tank reactors (STRs). This study quantitatively investigated how different mixing indices describe the mixing performance of a moving baffle OBR ...
