A Mixing-Based Design Methodology for Continuous Oscillatory Flow Reactors

Chemical Engineering Research and Design, 2002
Oscillatory flow reactors (OFR) have been actively developed over the last fifteen years at a number of UK universities, including the department of Chemical Engineering, University of Cambridge. OFRs exploit the uniform and efficient vortex mixing that can be achieved when an oscillatory fluid motion interacts with orifice plate baffles in a tube. One

Analysis of axial dispersion in an oscillatory-flow continuous reactor

Chemical Engineering Journal, 2003
Abstract Experimental results of axial mixing for single-phase flow in pulsed sieve plate column (PSPC) were presented and discussed. The study is aimed at the use of the PSPC as a new type of oscillatory-flow tubular reactor for emulsion polymerization processes.

Mass Transport and Residence Time Characteristics of an Oscillatory Flow Electrochemical Reactor

Chemical Engineering Research and Design, 1999
The mass transport and residence time characteristics of a parallel-plate oscillatory flow reactor have been investigated by studying the reduction of ferricyanide under an array of experimental conditions, including variations in oscillation frequency, oscillation amplitude, net flow rate and flow geometry.

Synthesis of palm based biolubricant in an oscillatory flow reactor (OFR)

Industrial Crops and Products, 2014
Plant-based oils are drawing great attention as potential alternative biodegradable lubricant base stocks with their attractive properties of being renewable, non-toxic and environmentally friendly. In the present study, oscillatory flow mixing (OFM) technology was applied in the production of palm biolubricant via transesterification of palm methyl ...

Process intensification of biodiesel production using a continuous oscillatory flow reactor

Journal of Chemical Technology & Biotechnology, 2003
AbstractOscillatory flow reactors (OFRs) are a novel type of continuous reactor, consisting of tubes containing equally spaced orifice plate baffles. An oscillatory motion is superimposed upon the net flow of the process fluid, creating flow patterns conducive to efficient heat and mass transfer, whilst maintaining plug flow.

Residence time distribution enhancement in reactors using oscillatory flow

Chemical Engineering Research & Design, 1996
In this paper the published and ongoing research concerning oscillatory flow in baffled tubes is reviewed. A number of key features are identified. Using this technology it is possible to achieve a near plug flow behaviour and a long residence time with a relatively short tubular reactor.

Mechanism of the oscillatory decomposition of the dithionite ion in a flow reactor

Chemical Communications, 2002
A simple mechanism consisting of three protonation equilibria and seven redox reactions between sulfur species can describe the large amplitude-sustained temporal pH-oscillations observed during acid-induced decomposition of the dithionite ion in a continuous-flow stirred tank reactor (CSTR) in the temperature range 25-60 degrees C.

Oscillatory Instability of a Plug Flow Reactor: A Heterogeneous Liquid-Liquid System

Russian Journal of Physical Chemistry B, 2019
A mathematical model of the dynamic behavior of a heterogeneous liquid-liquid reaction system in a plug flow reactor is formulated. Numerical investigation of the oscillatory instability of the reactor is carried out. The region of oscillatory regimes in a parametric space is examined for the Semenov parameter — the temperature at the entrance to the ...
