Abstract
A process for the conversion of plastics to chemicals includes, in part: providing a plastics stream (A) including polyvinyl chloride (PVC); supplying the plastics stream (A) and a solvent (S) to a reactor vessel (); subjecting the plastics in the reactor vessel to a temperature of ≥250° C. to <350 under applying a vacuum or using an inert gas sweep, and evacuating the generated hydrogen chloride (B) from the vessel, wherein the PVC is partially dechlorinated to form a plastics stream (C) including partially unsaturated PVC; removing the plastics stream (C) including partially unsaturated PVC from the reaction vessel; separating in a separation system () at least a part of the partially unsaturated PVC from the plastics stream to form a dechlorinated plastics stream (D) including the solvent; and combining the stream (D) with an atmospheric residue stream (N) to obtain a stream (O).
