| Abstract: | The terminal velocities of single drops of four different solvents were measured in a pulsed-sieve-plate column (50 mm. i. d.) with standard cartridge, correspondent correlation is suggested. The effect of circulating turbulence of continuous phase between plates due to pulse on the motion of drops was observed and investigsted. Comparing the experimental data with those characteristic velocities of swarm of drops published in literature, a correlation is proposed to correlate the characteristic velocity (V0) in pulsed-sieve-plate column, the terminal velocity (VD) of single drop and diameter (d) of the drop. Then it is hopeful to develop a method for determination of the mean diameter of drops in column under various operation conditions from the measurement of the corresponding characteristic velocity. |
