AB  - A detailed transient tridimensional CFD model of the turbulent flow of liquid phase inside of 26 mm diameter continuous oscillatory baffled reactor (COBR) was developed using STAR CCM+ software. The model considered a large number of COBR cavities separated with single-orifice baffles. The CFD model was validated using residence time distribution experiments with several flowrates and frequencies. Different from previous studies, flow oscillations in our work were generated using a membrane pump, which enabled lower amounts of backflow. Simulations were used to analyse flow patterns and mixing for several values of inlet flowrate and oscillation frequencies.

AB  - Transition from batch to continuous processing is an attractive alternative for the production of pharmaceutical, fine and bio chemicals. In a number of such industrial reactions or separations, a solid phase is present either as a reactant, product or catalyst. Instead of conventional continuous reactors, the utilization of oscillatory flow reactors could be advantageous. The flow pattern of solids in a continuous oscillatory baffled reactor (COBR), into which solids are introduced continuously, was investigated experimentally and theoretically. The effects of operating conditions on a solids flow regime, solids mean residence time and dispersion and solids holdup were analyzed and quantified. Four solids flow regimes named as: Creeping solids flow, Dense solids flow, Dilute solids flow and Solids washout, were identified based on the ratio of the maximum oscillatory axial velocity to hindered settling velocity of particles, input power per volume for oscillatory flow and the concentration ratio between adjacent cells. The results demonstrate that increasing frequency and/or amplitude decreases the axial dispersion of solids, the ratio of solids to fluid mean residence time and the solids holdup. Inlet solids concentration has no significant influence on the axial dispersion but considerably affects the solids mean residence time and the solids holdup.

AB  - BACKGROUND: Oscillatory baffled reactors have good prospect for use in batch to continuous transition for many industries. For reliable design and scale up it is essential to mathematically describe mixing and flow pattern of oscillatory flow. The aim of this study is to investigate the effects of operating conditions on residence time distribution (RTD) of liquid phase in a continuous oscillatory baffled reactor (COBR) and to propose a correlation that accurately describes the flow pattern. RESULTS: Analysis of results obtained for a wide variety of operating conditions in two geometrically similar reactors show that increase of oscillation frequency and amplitude both decrease axial dispersion, with a more prominent effect of amplitude. Proposed power-law correlation is in very good agreement with all performed experiments. Peclet numbers predicted by this correlation are in reasonably good agreement with the literature experimental data and is much better than the ones obtained by the commonly used correlation, which contains more fitting parameters. CONCLUSION: Results show that relatively high amplitudes, low frequencies and low to moderate secondary non-oscillatory flow should be used to ensure effective mixing with a low net flow in COBR. Developed correlation offers a simple, yet reliable way to predict the macroscopic flow pattern of liquid in COBR.

AB  - In production of cigarettes a lot of tobacco waste, with nicotine, goes into the environment. Hence, there is a need for an economic and efficient method to diminish the discharge of hazardous materials from tobacco wastewaters. Bioaugmentation using specialized bacteria strains could improve the efficiency of tobacco wastewater treatment. In this review paper we present bioaugmentation methods for tobacco wastewater treatment that were published in last few years. Bioaugmentation systems have proven to be very effective in removal of nicotine and TOC; it was shown that Pseudomonas sp. HF-1 and TW bacteria strains can be successfully used in reactors. Recent studies showed that controlling pH in the reactors can improve reactor performance in removing nicotine and TOC from tobacco wastewater.

AB  - Global market competition, increase in energy and other production costs, demands for high quality products and reduction of waste are forcing pharmaceutical, fine chemicals and biochemical industries, to search for radical solutions. One of the most effective ways to improve the overall production (cost reduction and better control of reactions) is a transition from batch to continuous processes. However, the reactions of interests for the mentioned industry sectors are often slow, thus continuous tubular reactors would be impractically long for flow regimes which provide sufficient heat and mass transfer and narrow residence time distribution. The oscillatory flow reactors (OFR) are newer type of tube reactors which can offer solution by providing continuous operation with approximately plug flow pattern, low shear stress rates and enhanced mass and heat transfer. These benefits are the result of very good mixing in OFR achieved by vortex generation. OFR consists of cylindrical tube containing equally spaced orifice baffles. Fluid oscillations are superimposed on a net (laminar) flow. Eddies are generated when oscillating fluid collides with baffles and passes through orifices. Generation and propagation of vortices create uniform mixing in each reactor cavity (between baffles), providing an overall flow pattern which is close to plug flow. Oscillations can be created by direct action of a piston or a diaphragm on fluid (or alternatively on baffles). This article provides an overview of oscillatory flow reactor technology, its operating principles and basic design and scale-up characteristics. Further, the article reviews the key research findings in heat and mass transfer, shear stress, residence time distribution in OFR, presenting their advantages over the conventional reactors. Finally, relevant process intensification examples from pharmaceutical, polymer and biofuels industries are presented.
