A correlation for drop size and slip velocity in reciprocating plate column

Bioprocess Engineering, 1998
Drop size distributions, mean drop diameter and slip velocity are experimentally studied in a reciprocating plate column. The correlations for the above are presented in terms of plate geometry, flow rates of phases and physical properties of the system covering a wide range in experimental conditions.

Gas—liquid pressure drop studies in a reciprocating plate column

The Canadian Journal of Chemical Engineering, 1986
AbstractTwo‐phase pressure drop in a 93 mm diameter reciprocating plate column (RPC) was studied for the air‐water system, and to a lesser extent for air‐kerosene. Amplitudes (strokes) in the range 14 to 63.5 mm and frequencies from 0.75 to 4.0 Hz were investigated for between 2 and 10 brass plates with hole diameters from 3 to 8 mm and free flow area ...

Apparent and true longitudinal concentration profiles in reciprocating plate column

Bioprocess Engineering, 1993
Mass transfer for kerosene-water system with benzoic acid and n-butyric acid as solutes has been studied in a reciprocating plate column at different operating conditions including the agitation rate of the plate stack, the plate geometry, the flow rates of the phases and the direction of mass transfer.

Gas liquid contacting in reciprocating plate columns: I. hydrodynamics

The Canadian Journal of Chemical Engineering, 1991
AbstractThe hydrodynamic characteristics of a 10‐cm reciprocating plate column used for counter‐current gas‐liquid contacting was investigated. The values of gas holdup, interfacial area and maximum throughputs achievable in this unit put it in a favourable position in comparison with other types of contactors.

Hydrodynamic investigations of gas–liquid contacting in a reciprocating plate column

The Canadian Journal of Chemical Engineering, 1986
AbstractThe maximum pressure variation at the bottom of a reciprocating plate column of the Karr type was investigated in single phase liquid and two phase gas–liquid systems. In the gas–liquid system the gas hold‐up was also measured. The power consumption was calculated on the basis of the pressure variation at the bottom of the column.It was shown ...

Back mixing in a reciprocating plate column with stable density gradients

AIChE Journal, 1998
AbstractAxial dispersion coeficients were measured in an aqueous phase flowing downward through a 5.08‐cm‐dia. Karr‐type reciprocating plate column. The steady tracer injection method was used, in which the concentration profile was measured upstream of tracer injection.

Performance and Scale-up of Karr Reciprocating Plate Extraction Columns

Industrial & Engineering Chemistry Research, 2008
The hydrodynamic and mass transfer performance of Karr reciprocating plate extraction columns with varying column diameters has been presented in order to examine how column performance changes with scale. An ideal liquid system of kerosene/tributyl phosphate−phenol−water was initially studied using a 50 mm diameter Karr column.

Break-up of droplets in Karr reciprocating plate extraction column

Chemical Engineering Science, 1987
Abstract The breaking rate of individual drops was investigated in a Karr type reciprocating plate extraction column. The binary systems used were: water-1,2-dichloroethane, water-toluene and water- n -butanol. The breakage probability and the conditional probability of breaking-up into a given number of daughter droplets, as well as the drop size ...
