Abstract

A novel type of extraction column has been constructed in which liquid pulsations are produced without the need for any mechanical moving parts. The factors governing the frequency and amplitude of the pulsations are discussed briefly. The effects of pulsation upon the extraction of acetic acid from kerosene by water in a packed column have been measured. The pulsations increase the number of transfer units by as much as threefold, a result similar to the observations of previous workers who used conventional pulsators having moving parts.

Abstract

On a fabriqué un nouveau genre de colonne d'extraction, dans laquelle les pulsations liquides se font sans exiger des parties mécaniques mobiles. On discute brièvement les facteurs qui régissent la fréquence et l'amplilude des pulsations. On a mesuré les effets des pulsations sur l'extraction par l'eau de l'acide acétique du kérosène dans une colonne garnie. Les pulsations augmentent le nomb're d'unités de transfert d'au moins trois fois; ce résultat est semblable à ceux qu'ont déja observés des chercheurs en employant des pulsateurs ordinaires avec parties mobiles.
