This paper describes an application of a direct adaptive control scheme to a pulsed liquid-liquid extraction column. Liquid-liquid extraction has been increasingly used in several industries as a separation technique. It performs a high degree of purification and is not heavy on energy. In spite of

Liquid extractions of benzoic acid-toluene solutions by means of water were studied under varying flow rates of both solvents in a 2-in. perforated-plate column to which pulsations of different frequencies and amplitudes were applied. Studies on reversal of the phase of the dispersion were made. Wit
Classically, sinusoidal oscillations are imposed to enhance mixing and mass transfer between two phases contacted. But, in any case of solid-liquid contact, it was noticed that this pulsation mode was not efficient enough to allow a controlled behavior of the solid phase. The problem is particularly
