Inventor(s) include Haroun, Yacine; Girardon, Stephane; Mejia Mendez, Deisy; and Weiss, Wilfried.
The application for the patent was published on Oct. 31, under issue no. 44/2025.
According to the abstract released by the Intellectual Property India: "The present invention relates to a process for treating a plastic feedstock, comprising: a) dissolution of the plastic feedstock in a dissolution solvent, between 100 C and 300 C and between 1.0 and 100.0 MPa absolute, to obtain a crude polymer solution; b) decantation of the crude polymer solution, to obtain a decanted polymer solution and a tailings fraction, step b) being carried out at 100-300 C and at 1.0-100.0 MPa absolute and using at least one decanter, an effluent enriched in polymer solution being recovered at the outlet of the or each decanter so as to constitute said decanted polymer solution, a tailings stream being recovered at the outlet of the or each decanter so as to constitute said tailings fraction, the liquid surface velocity in said decanter ranging between 1 10-7 and 1.000 10-2 m/s; c) solvent-polymer separation, to obtain a stream of purified thermoplastics. The present invention also relates to a device for carrying out such a process."
