SOLUTION FRACTIONATION METHOD Russian patent published in 1999 - IPC

FIELD: liquids' separation methods. SUBSTANCE: invention relates to chromatographic method with imitating moving bed wherein liquid flows in a system containing al least two beds of subdivided charge in unlike ionic forms. Fractions enriched with different components are collected during sequential process including admission, elution, and recycling phases. Liquid contained in beds of subdivided charge with its dry substance- concentration profile recycles in recycling phase within loop containing one, two, or more beds of subdivided charge. Such method can be, for example, used to fractionate sulfite cooking liquor, molasses, and distillery dregs. EFFECT: simplified procedure. 30 cl, 4 dwg, 6 tbl
