Abstract
L'INVENTION CONCERNE UN PROCEDE PERFECTIONNE D'ENTRAINEMENT D'UN LIQUIDE VAPORISABLE, D'UNE DISPERSION AQUEUSE D'UN POLYMERE, DANS LEQUEL LA DISPERSION AQUEUSE DESCEND DANS UNE COLONNE D'EPUISEMENT TANDIS QU'UN FLUIDE D'ENTRAINEMENT S'ELEVE DANS LA MEME COLONNE DONT LES PLATEAUX SONT POURVUS DE DEVERSOIRS. LES DEVERSOIRS PORTES PAR LES PLATEAUX OCCUPANT AU MOINS LE TIERS INFERIEUR DE L'ENSEMBLE ONT UNE HAUTEUR D'AU MOINS ENVIRON 10CM MAIS N'EXCEDANT PAS 30CM ET LES DEVERSOIRS PORTES PAR UN NOMBRE DE PLATEAUX NE REPRESENTANT PAS PLUS DES DEUX TIERS SUPERIEURS DE L'ENSEMBLE ONT UNE HAUTEUR D'AU MOINS ENVIRON 5CM, MAIS N'EXCEDANT PAS 30CM. APPLICATION A L'ELIMINATION PAR EPUISEMENT DU STYRENE D'UN LATEX BUTADIENE-STYRENE.
