Design Concept of a Sieve Plate Distributor for Liquid-Liquid Extraction - Part 2: Validation of the Design Concept in a Technical-Scale Column

“…The method of operation of the mill was described in [1,2], the heat dissipation is ensured by a double-shell reactor.…”

“…The drop size distribution is measured with the capillary suction method [1], the measurement of the phase distribution will be described below. In every support ring the drop size distribution and the phase distribution is measured over the cross section of the column.…”

Simulated and Experimental Dispersed-Phase Breakage and Coalescence Behavior in a Kühni Liquid−Liquid Extraction ColumnSteady State

“…The extraction column was equipped with measurement devices that allowed the investigation of the hydrodynamic conditions along the column. A photoelectric technique, initially developed by Pilhofer in ref , was used to measure the axial drop-size distribution profiles. The drop slug length in a capillary was determined with two pairs of photoelectric cells on a calibrated capillary.…”

“…All these data, as well as the intensity of agitation and the flow rates of the dispersed and continuous phases, were recorded on-line using a personal computer. Experimental results were obtained as data files created by Hydromess , a computer program developed at the University of Clausthal and implemented at the University of Munich's pilot-scale Kühni column. From a collection of 1000-drop size measurements, this program computes number, volume, and surface area drop-size distributions and mean diameters.…”

Design Concept of a Sieve Plate Distributor for Liquid-Liquid Extraction – Part 1: Laboratory-Scale Experiments and Design

“…For different tubular distributors (Fig. 1) the droplet distribution was measured with the photoelectric suction method [3] and compared with each other. The investigated operation range was defined with the beginning of droplet generation at every orifice of the distributor as the lowest flow rate and the onset of spraying as the upper limit.…”
