POWER CONSUMPTION IN A RECIPROCATING PLATE EXTRACTION COLUMN.

Power consumption in a 150 mm diameter Karr reciprocating plate column has been determined by two different but consistent methods, namely force-displacement diagrams at moderate velocities of oscillation and a wattmeter technique at high velocities. The accuracy of the methods is estimated to be plus or minus 10%. Amplitudes in the range 3. 17 to 12. 7 mm and frequencies from 0. 5 to 6. 9 Hz have been investigated for stainless-steel plates …
