A pulsed perforated-plate column is controlled by varying the operating conditions as the pulsing conditions, the initial loading conditions, the A/O ratios and the flow rates of inlet and outlet streams. Changing these variables causes the holdup to vary with position in the column. As a result, it is necessary to know the axial holdup in order to obtain complete dynamic mass transfer equation.
In the present paper, the axial holdup of dispersed phase in a pulsed perforated-plate cdumn, pulser feeder type, is studied. The column is made of Pyrex glass, 5cm I.D. and 100cm in actual length. Both nozzle plates and sieve plates with same cartridge geometries are used in the column. The liquid system is TBP in kerosene-water. The axial holdup data are obtained in the dispersed aqueous and the dispersed organic modes. Experimental results show that the plate-type affect the axial holdup distribution. The tendency of the axial holdup to the nonuniformity is counteracted by the nozzle plate.
