Abstract
A method for purifying a mixture in a multicolumn chromatography system. The method successively and cyclically collects a raffinate, injects the mixture to be separated, collects an extract, and injects eluent. The mixture to be separated contains fructose and has a dry matter mass concentration of 45 to 55%. The method is carried out at a temperature of 50 to 62° C.
Claims16
A method for purifying a mixture to be separated containing fructose in a multicolumn chromatography system comprising a plurality of columns and intercolumn fluidic links, the method comprising successively and cyclically:
- a step of collecting a raffinate from the multicolumn chromatography system, a step of injecting the mixture to be separated containing fructose into the multicolumn chromatography system, a step of collecting an extract from the multicolumn chromatography system and a step of injecting eluent into the multicolumn chromatography system;
- wherein the method comprises moving a fluid through the intercolumn fluidic links at a velocity greater than 0.5 m/s;
- wherein the mixture to be separated containing fructose has a dry matter mass concentration of 45 to 55%, the method being carried out at a temperature of 50 to 62° C.;
- the injected volume of eluent is from 0.12 to 0.28 BV;
- and
- the extract contains a mass proportion of fructose, relative to the total dry matter, greater than or equal to 95%.
