Abstract

See full text

The invention relates to a method for purifying a mixture to be separated, in a multicolumn chromatography system, the method comprising successively and cyclically:

    a step of collecting a raffinate, a step of injecting the mixture to be separated, a step of collecting an extract and an eluent injection step, at an operating temperature;wherein the mixture to be separated has a viscosity at 20° C. greater than or equal to 3 mPa·s; and wherein the dry matter mass concentration of the mixture to be separated is equal, within 5%, to a threshold concentration, said threshold concentration is such that:the viscosity of the mixture to be treated at a dry matter mass concentration equal to the threshold concentration and at the operating temperature, is equal to twice the viscosity of the mixture to be treated, at a dry matter mass concentration equal to 85% of the threshold concentration and at the operating temperature.
