FIELD: process engineering.SUBSTANCE: invention relates to chromatography. It covers continuous or quasi-continuous cleaning of multicomponent mix (Fd). Hear used are at least four separate chromatographic columns where through forced is initial mix using at least one solvent. Multicomponent initial mix (Fd) is to be divided in integer number (n) of fractions (Fi), where n equals at least 5. Said columns are grouped to least six (?, ?, ?, ?, ?, ?, ?, ?). Note here that every section (?, ?, ?, ?, ?, ?, ?, ?) includes at least one column proved that functions of said sections can be performed sequentially and by separate columns. There are at least two collection sections, at least two circulation sections (?, ?, ?), collection section (?) for collection of strong adsorbate section and feed section (?). Functions of sections (?, ?, ?, ?, ?, ?, ?, ?) are performed either in synchronism or serially. On elapse or during time (t*) said columns are displaced in direction opposite the main direction of displacement of the solvent. First column of every collection section (?, ?, ?) displaces to the last position of appropriate circulation section (?, ?, ?). First section of upstream circulation section (?) displace to first position of collection section (?) to collect said strong adsorbate. First columns of the next circulation channels (?, ?, ?) displace to the last positions of the next upstream connection sections (?, ?, ?). First column of collection section (?) for strong sorbate collection displaces to the last position of feed section (?), while first column of said feed section (?) displaces so that its renders the last column of downstream collection section (?).EFFECT: separation of true multicomponent mixes into.15 cl, 14 dwg, 4 tbl |
