FLOODING CHARACTERISTICS AND SEPARATION EFFICIENCIES OF PULSED SIEVE-PLATE EXTRACTION COLUMNS. Experimental Data Applied to Design of Extraction Columns
Generalized flooding and mass transfer correlations were developed from experimental data for pulsed sieveplate extraction columns. The flooding correlation is based on 665 data points and permits the prediction of total flooding velocities with an average deviation of 20% from the experimental values for systems in which water is the continuous phase. The mass transfer correlation is based on 285 data points and permits the prediction of over-all transfer unit heights with an average deviation of 16.4% from the experimental values. This correlation applies to systems in whlch mass transfer occurs from the dispersed phase to the aqueous continuous phase and where the major resistance to transfer is in the dispersed phase. Nomographs facilitate design calculations. (auth)
