Abstract

See full text

The invention related to a method for purifying a first fatty acid, preferably polyunsaturated, using an initial mixture further comprising at least one second fatty acid, optionally a third fatty acid and optionally a fourth fatty acid, with the method comprising:

    a first step of chromatographic separation in liquid phase, using the initial mixture, carried out in a first unit for chromatographic separation, making it possible to recover on the one hand a first flow enriched with a first fatty acid and on the other hand a flow enriched with a second fatty acid,optionally, a second step of chromatographic separation in liquid phase, using the first flow enriched with a first fatty acid, carried out in a second chromatographic separation unit, making it possible to recover on the one hand a second flow enriched with a first fatty acid and on the other hand a flow enriched with a third fatty acid;optionally, a third step of chromatographic separation in liquid phase, using the third flow enriched with a first fatty acid, carried out in a third chromatographic separation unit, making it possible to recover on the one hand a third flow enriched with a first fatty acid and on the other hand a flow enriched with a fourth fatty acid;at least one among the first unit for chromatographic separation, the second unit for chromatographic separation and the third unit for chromatographic separation being a static bed chromatographic separation unit with a single column with recycling in stationary state.
