Abstract
PROCEDE ET APPAREIL POUR L'EXTRACTION EN ECOULEMENT, DANS LEQUEL UNE SUBSTANCE DISSOUTE DANS UN PREMIER SOLVANT EST EXTRAITE A L'AIDE D'UN SECOND SOLVANT QUI EST INSOLUBLE DANS LE PREMIER. LES DEUX SOLVANTS SONT AMENES ENSEMBLE PAR DEUX BRANCHES D'UN TUBE ENT, ET LE MELANGE SORT PAR LA TROISIEME BRANCHE, LES SECTIONS DES BRANCHES ETANT DIMENSIONNEES DE FACON A PRODUIRE UN ECOULEMENT SEGMENTE AVEC DES BOUCHONS ALTERNES DU SECOND ET DU PREMIER SOLVANT. LE RAPPORT ENTRE LES SECTIONS DES BRANCHES DU TUBE POUR LE PREMIER ET LE SECOND SOLVANT EST DE 2-8:1 ET DE PREFERENCE DE 4:1. ENTRE LA PREMIERE ET LA TROISIEME BRANCHE AMENANT LES COURANTS CONFLUENTS, LE RAPPORT ENTRE LES SECTIONS EST REDUIT A 0,7-1,2:1, ET DE PREFERENCE 1:1, A UNE DISTANCE DE LA JONCTION QUI EST DE 1 A 3 FOIS LE DIAMETRE INTERNE DE LA TROISIEME BRANCHE. LE COURANT CONFLUENT EST AMENE PAR UN TUYAU EN SPIRALE, PRODUISANT UNE FORTE EXTRACTION EN RAISON DE LA TURBULENCE A CONTRE-COURANT.
