“…From these values, it can be observed that for a given extraction factor, the (HTU)oa, value is higher for higher plate spacing, and so (K-a) is lower. Many authors (Moulton and Walkey, 1944; Mayfield and Church, 1952; Nandi and Ghosh, 1950;Pyle et al, 1950;Treybal and Dumoulin, 1942) have observed that decreased plate spacing resulted in improved rates of mass transfer and the present results are in conformity with their observations.…”

“…In fact, the average % error for these 16 runs changed from 50% to 39%. This is in agreement with Pyle et al (1950), who found experimentally that a decrease in the number of holes per plate results in a decrease in the plate efficiency.…”

This paper presents the first known data on extraction with oscillating droplets in a perforated-plate column. The capacity coefficient increases with flow rate of either phase and with increasing number of plates (from 3 to 7) in a fixed column height. Comparison is made between the number of plates actually used to achieve a given extraction and those predicted by the provisional design procedure of Skelland and Conger. The results are considered to be gratifying.

“…Moulton and Walkey (1944) used gasoline/methyl ethyl ketone/water and worked with high concentrations to produce large volume changes of the phases. Pyle et al (1950) worked with the ethyl ether/acetic acid/water system to study influences of hole diameter, percent hole area, tray spacing, solvent/feed ratio, and flow rate on the capacity and efficiency of a 0.219-m (8.6-in.) column.…”
