The invention relates to a method for producing a polyester terephthalate from at least one polyester filler to be recycled, incorporating a depolymerization method, advantageously by glycolysis, of the polyester to be recycled in order to produce a diester intermediate which is compatible with the specifications of the polymerization steps and comprising an optimized flow recycling system.

Concurrent cyclone extractor

Concurrent cyclone extractor

Concurrent cyclone extractor separator comprising: - a vessel (1) of elongate shape along an axis (X), of substantially circular section of inner diameter D1, of length L1, comprising at the first end means for introducing gas/solid mixture MA through a so-called external entry (4), the said means making it possible to impart, at least to the light phase LA of the mixture MA, a helical movement in the direction of flow of the mixture MA in the said vessel, - a so-called inner vessel (2), of elongate shape along the axis (X), of substantially circular section of diameter D2 which is smaller than D1, of length L2 which is smaller than L1, whose end close to the external entry (4) situated at a distance LS which is smaller than L1 from the outermost level of the external entry (4) forms the so-called internal entry (5) through which at least a proportion of the light phase LA enters, the said vessel being extended by at least one conduit (6), making it possible to remove the light phase LA separated outside the first external vessel, - a so-called second external vessel (3), of diameter D1, which has a substantially vertical axis of symmetry, connected to the said first vessel by an opening of diameter D1, the said second vessel collecting the dense phase DA separated from the mixture MA, which comprises means (10) for injecting a light extraction phase LB, the injection taking place countercurrentwise to the flow of the separated dense phase and at least partially into the said dense phase, which is at least partially fluidised, and comprises at least one exit (12) for the recovery of the at least partially desorbed dense phase DA.
