Disclosed is a process for the resolution of a mixture into at least one first fraction and one second fraction, the respective compositions of said fractions differing by at least one element. The process further comprises at least one elementary stage of fractionation, in which at least two inflows are placed in contact, these two flows being a first inflow (10) with low first fraction content, notably in counter-current, and a second inflow (11) with low second fraction content. Two outflows are obtained, said flows being a first outflow (12) enriched in first fraction with respect to the first inflow (10), and a second outflow (13) enriched in second fraction with respect to the second inflow (11). According to the invention, the elementary fractionation stage, which is non-static, is implemented in an elementary fractionation run, at which point at least one mass exchange buffer supply (15) is accumulated, and the elementary stage of fractionation is periodically initiated and repeated.
Ce procédé de résolution d'un mélange en au moins une première fraction et une deuxième fraction, différentes par leurs compositions respectives en au moins un élément, comprend au moins une étape élémentaire de fractionnement, selon laquelle on met en contact au moins deux flux entrants, à savoir un premier flux entrant (10) pauvre en première fraction, notamment de contre-courant, et un deuxième flux entrant (11) pauvre en deuxième fraction, pour obtenir deux flux sortants, à savoir un premier flux sortant (12) enrichi en première fraction, par rapport au premier flux entrant (10) et un deuxième flux sortant (13) enrichi en deuxième fraction par rapport au deuxième flux entrant (11). Selon l'invention, l'étape élémentaire de fractionnement, non stationnaire, est mise en oeuvre dans un étage élémentaire (14) de fractionnement, au niveau duquel on accumule un volume tampon (15) d'échange de masse au moins, et l'étape élémentaire de fractionnement commandée et répétée périodiquement.
