Definitions
- the present invention relates to a method for purifying a plastic solution, and to a recycling method using the same.
- centriiugal settling preferably occurs :
- the method in the case of spray drying (as in application WO 03/05464 also in the name of the Applicant) or of devolatilization (as in application FR 04.03856 also in the name of the Applicant), it may be a continuous method. Whether the method is continuous or semi-continuous, it operates preferably in a closed loop, with effluent recycling.
- centrifugal settling according to the invention is preferably incorporated in a PVC recycling method by dissolution using an effluent mainly comprising MEK, water and hexane.
- an effluent mainly comprising MEK, water and hexane since the total water content of the medium is generally at least 5 % (by weight), a hexane content of at least 15 % should be selected (it is being understood that the rest of the medium consists of MEK) in order to obtain an MEK-rich phase capable of dissolving the PVC over an acceptable temperature range.
- Wastes used for the tests 1.
- Cables low- voltage and telecom cable waste comprising PVC and metal, rubber, PE, etc.
- Blister packs waste comprising PVC and PE.
