Abstract
The present invention concerns a fractionation process of a mixture by elution chromatography. It is characterized in that the collected eluent is purified, restored to supercritical state and recycled in the head of the column. It concerns a cracking process of mixtures by elution chromatography with liquid in the supercritical state and an installation for its operation.
