ABSTRACT:
Disclosed is a cocurrent cyclone separator extractor for both the separation of a gas/solid mixture into at least one light phase, and for the extraction of gases sorbed by the solid, comprising a first elongated external enclosure, which has a substantially circular cross-section, having at a first end, external inlet means for the introduction of the mixture, said means making it possible to give at least to the light phase a helical movement in the flow direction of the mixture in said enclosure; an elongated second enclosure, which has a substantially circular cross-section of smaller diameter than the first enclosure, whose end close to the inlet means; and a second external enclosure having a substantially vertical axis of symmetry, connected to said first enclosure, said second enclosure collecting the separated dense phase and having means for the injection of a light extraction phase, injection taking place in countercurrent manner with respect to the flow of the separated dense phase and, at least in part in said dense phase which is at least partly fluidized, the above-mentioned components arranged so that injection of light extraction phase limits flow of light phase in the direction of said second enclosure, and said second enclosure has at least one outlet for the recovery of the at least partly desorbed dense phase, said inlet also functioning as a removal means for said light extraction phase.
