Zusammenfassung:A process and system for liquefying and dehalogenating a waste plastic are provided. Generally, the process comprises: (a) liquefying solid waste plastic to produce a liquefied waste plastic; (b) heating at least a portion of the molten waste plastic in a heat exchanger to thereby provide a heated liquefied waste plastic; (c) sparging a stripping gas into the heated liquefied waste plastic to produce a multi-phase mixture; and (d) disengaging a gaseous phase from a liquid phase of the multi-phase mixture to thereby provide a halogen-enriched gaseous material and a halogen-depleted liquefied waste plastic.
