Abstract
Perturbations are corrected in the compositions of an extract (EA) or raffinate (RB) due to the dead volume introduced by at least one recycling pump (P) for a liquid, supercritical or gaseous mixture in a closed circuit of column sections, or due to a degradation in their separating power each time an injection or extraction stream passes from a position anterior to a position posterior to each of the dead volumes in the circuit or each section whose separation power has been degraded. Firstly, the connection period for said stream to the circuit is increased by an appropriate value, and then when the stream passes from the posterior position to the dead volume, or connection to the degraded section, to the following position, the connection period is reduced so that the period regains the value which would have been applied if each of the dead volumes had been ignored or the degradation in the separation powers had been ignored.
