Title (EN) IMMISCIBLE LIQUID SEPARATOR
(FR) SEPARATEUR DE LIQUIDES NON-MISCIBLES
Abstract: front page image
(EN)Apparatus for separating immiscible liquid mixtures, such as oil-water mixtures, includes a closed loop tubular enclosure (20) having a liquid mixture inlet (22) and independent liquid outlets (22) and (32) spaced from each other and from the inlet (22). The inner cross section area of the enclosure (20) has a first reduced portion (28) adjacent the first outlet (22) and a second further reduced portion (33) adjacent the second outlet (32). Selectively absorbent elements (40) are driven around within the enclosure, preferably by the pressurized liquid mixture, for selectively absorbing the liquid mixture and selectively discharging one of the liquids through the first outlet (22) upon mild compression by the first reduced portion (28) and the other of the liquids through the second outlet (32) upon higher compression by the second further reduced portion (33). A third outlet (34) with a still further reduced portion (35) may be provided for discharging the remaining portion of the other liquid. The final reduced portion (35) also provides a differential piston hydraulic driving force for the selectively absorbent elements (40) and also prevents backflow from the inlet (22) directly to the last outlet (34).
(FR)Appareil de separation de melanges liquides non miscibles, tels que des melanges huile-eau, comprenant une enceinte tubulaire a boucle fermee (20) ayant une entree du melange liquide (22) et des sorties independantes de liquides (22 et 32) espacees entre elles et espacees de l'entree (22). La section interieure du tube (20) possede une premiere portion reduite (28) adjacente a la premiere sortie (22) et une seconde portion plus reduite (33) adjacente a la seconde sortie (32). Des elements absorbants (40) sont entraines dans le tube, de preference par le melange liquide sous pression, pour absorber selectivement le melange liquide et refouler selectivement l'un des liquides au travers de la premiere sortie (22) lors d'une legere compression par la premiere portion reduite (28) et l'autre liquide au travers de la seconde sortie (32) par compression plus forte due a la seconde partie plus reduite (33). Une troisieme sortie (34) avec une portion encore plus reduite (35) peut etre prevue pour decharger ce qui reste de l'autre liquide. La partie reduite finale (35) contient un piston differentiel qui exerce une force d'entrainement hydraulique pour les elements absorbants selectifs (40) et empeche un retour d'ecoulement depuis l'entree (22) directement vers la derniere sortie (34).
