EFFECT OF PRESSURE ON MASS TRANSFER IN THE GAS PHASE (thesis)
(((((Abstract unscannable)))))) l5066 Longitudinal dispersion (axial mixing) was studied for counter-current fiow of liquids through packed beds, using six different combinations of packing type and size and bed arrangements. The Peclet number, used as a coefficient, was measured in both the continuous and the discontinuous phase of the systems kerosene in water, water in kerosene, and water in mineral oil. The observed values ranged from 100 to 10% of the Peclet number measured for the same packing in single-phase laminar flow. Peclet numbers for each phase were correlated as a function of the two flow rates. An effect of packing diameter and sphericity on the continuous-phase Peclet number was also found. Different mechanisms were indicated for dispersion in the discontinuous phase, depending upon whether or not that phase wets the packing. (auth)
