Upping Column Extraction Efficiency by Pulse Application - Sieve Columns

A Rate Approach to Design of Perforated-Plate Extraction Columns

“…The)' postulate that transfer of solute out of a solvent to which it adheres by hydrogen bonding Figure 3. Comparison between actual and predicted numbers of plates required for the 65 separations in group A (Table VII gives some relevant details): <, data of Allerton, Strom, and Treybal (1943); O, data, of Garner, Ellis, and Fosbury (1953); 0/ data of Garner, Ellis, and Hill (1955); V, data of Goldberger and Benenati (1959); , data of Row, Koffolt, and Withrow (1 941); , data of Treybal and Dumoulin (1 942) occurs much less readily than from a solvent to which it is linked by the relatively weaker van der Waals forces. Thus, when transferring diethylamine in alternate directions between toluene and water, Garner, Ellis, and Hill (1955) found the transfer rate from toluene to be several fold greater than from water.…”

Scale-up of a Novel Mixer-Settler Extractor

“…Many articles (2-5, 7,8,[70][71][72] have been published on the process variables involved in mixersettler units, particularly those pulsing liquids through perforated plates or packing to get their mixing efficiency. The relative importance of these three areas in scale-up depends somewhat on the extractor design being studied.…”

Extraction with Oscillating Droplets in a Perforated-Plate Column

“…, but most experimental studies on laboratory or pilot-plant sieve-plate extraction columns appeared between 1940 and 1960 as follows: Allerton et al (1943); Garner et al ( , 1955; Goldberger and Benenati (1959); Mayfield and Church (1952); Moulton and Walkey (1944); Nandi and Ghosh (1950); Pyle et al (1950); Row et al (1941); and Treybal and Dumoulin (1942). wood et al, 1939) on various mass transfer and hydrodynamic features of drops forming, falling or rising, and coalescing in a second liquid phase.…”
