Title (EN) MULTIPLE FREQUENCY ELECTROSTATIC COALESCENCE
(FR) COALESCENCE ELECTROSTATIQUE A FREQUENCES MULTIPLES
Abstract: front page image
(EN)A method of augmenting the separation of immiscible heavier and lighter components of an emulsion including the steps of conducting the emulsion into a treatment vessel (10), providing an AC voltage source (46), employing from the source an AC voltage of at least one selected frequency F1 (42) to establish at least one electric field (28, 30) within the vessel (10) through which the emulsion passes, and cyclically modulating the AC voltage (42) with a method of modulation (44) selected from: (a) amplitude modulation; (b) frequency modulation; and (c) combined amplitude and frequency modulation.
(FR)L'invention concerne un procédé destiné à favoriser la séparation de composants immiscibles plus légers et plus lourds d'une émulsion, ledit procédé consistant à guider l'émulsion dans un récipient de traitement (10), à utiliser une source de tension en c.a. (46), à utiliser à partir de la source, une tension en c.a. d'au moins une fréquence sélectionnée F1 (42) pour établir au moins un champ électrique (28,30) à l'intérieur du récipient (10) traversé par l'émulsion et à moduler de manière cyclique la tension en c.a. (42) au moyen d'un procédé de modulation (44) sélectionné dans : (a) modulation d'amplitude ; (b) modulation de fréquence ; et (c) combinaison de modulation d'amplitude et de modulation de fréquence.
