Mass Transfer in Packed Liquid Extraction Towers.

Mass Transfer Studies in Wetted-Wall Extraction Towers.

“…The accessory equipment for the extraction tower is the same as that used in the companion article (11), except that a globe valve was used in place of the atmospheric vent. The wetted-wall column follows the design of Treybal and Work (15) with slight modifications, A diagram of the column with the separating end sections is shown in Figure 1.…”

“…Water, acetone, Pegasol, and toluene were from the same sources as in the companion article (11). Butyric acid (Naarden) was 99.8% pure, and benzoic acid (Baker's analyzed reagent grade) was 99.5% pure, determined by chemical analysis.…”

“…The equilibrium distribution data for these systems are available in the literature (8,9,11,12) and are listed in Table I and were used in calcuating mass transfer.…”

“…Values of over-all coefficients, and over-all heights of transfer units were calculated from the equation used in the companion article (11).…”
