Title:
PLASTIC PROCESSING METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/037592
Kind Code:
A1
Abstract:
A plastic processing method and system. The method comprises the following steps: S1, enabling plastic to be processed to enter a liquefaction unit for liquefaction treatment, so as to obtain a liquefied material; S2, performing thermal treatment on the liquefied material in a viscosity reduction unit to reduce the viscosity of the liquefied material, and obtaining a viscosity-reduced liquefied material; S3, enabling the viscosity-reduced liquefied material to enter a cracking unit for cracking, so as to obtain reaction oil gas; and S4, enabling the reaction oil gas to enter a separation unit for separation treatment. The system comprises a liquefaction unit, a viscosity reduction unit, a cracking unit, and a separation unit.
