Single drop breakage in a reciprocating plate column

Chemical Engineering Journal, 2021
Abstract Single drop breakage was investigated in a lab-scale reciprocating plate column. A high-speed camera was used to capture the drop breakage process and drop interactions with the plate. Image processing was completed to collect information on breakage location, breakage probability, breakage time and number of daughter drops under different ...

THE RECIPROCATING PLATE COLUMN—DEVELOPMENT AND APPLICATIONS

Chemical Engineering Communications, 1992
Abstract Reciprocating plate columns (RPCs) were first proposed in 1935 but most of the development has occurred in the past 30 years. Three types of RPC are in use in industry for liquid-liquid extraction, in diameters up to about 1·5  m: The Karr column (U.S.A.

Axial dispersion in a reciprocating plate column

Canadian Journal of Chemical Engineering, 1996
AbstractAxial mixing in a reciprocating plate column with different amplitudes has been investigated for single‐phase and two‐phase (air‐water) systems. Experiments were performed in water in a semi‐batch scheme (no water flow) in a 1.26 m high and 101.6 mm internal diameter column.It was found that the axial dispersion coefficient is a strong function

Heat transfer in a reciprocating plate column

Canadian Journal of Chemical Engineering, 2000
AbstractA pilot‐scale (5.08 cm internal diameter) reciprocating plate column has been modified by the insertion of a brass test section for heat transfer measurements. Heat is supplied to liquid (water or a glucose solution) in the column from an electrical heating tape wound round the brass section, the walls of which contain thermocouples ...

The use of an ionic liquid in a Karr reciprocating plate extraction column

Chemical Engineering Research and Design, 2012
Abstract Ionic liquids offer an alternative to volatile organic solvents for extraction of a range of materials. This work examines the mass transfer performance of a Karr reciprocating plate column with an ionic liquid as an alternative solvent for the extraction of phenol from water.

Hydrodynamics and power consumption of a reciprocating plate gas–liquid column

Canadian Journal of Chemical Engineering, 1993
AbstractAn experimental program has been initiated to use a reciprocating plate column for aerobic fermentations. This paper reports the results of the initial phase consisting of the hydrodynamic studies and the evaluation of the power consumption as a function of the level of agitation and gas superficial velocity.

ANALYSIS OF AXIAL MIXING IN A GAS-LIQUID RECIPROCATING PLATE COLUMN

Chemical Engineering Communications, 2007
Axial mixing in the continuous phase in a Landau reciprocating-plate column (LRPC) has been investigated for both single-phase and two-phase gas-liquid flow conditions. A hydrodynamic model is proposed in which axial mixing is described as a process consisting of a backflow through the plate plus longitudinal mixing within the stage.

Dynamic behavior of reciprocating‐plate columns

The Canadian Journal of Chemical Engineering, 1975
AbstractThe unsteady‐state behaviour of a reciprocating plate column in which adjacent plates move out of phase with each other has been studied experimentally by determining responses to step changes.The one‐dimensional, two‐parameter model developed, leading to a system of differential equations with time‐dependent coefficients, was simplified to ...
