Title:
DEPOLYMERIZATION SYSTEM HAVING COIL-WOUND HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2021/036257
Kind Code:
A1
Abstract:
A depolymerization system having a coil-wound heat exchanger (4) comprises: a heat exchange device used to heat a material; a gas-liquid separation device (1) connected to a material output end of the heat exchange device; and a depolymerization reactor (2) connected to a gas output end of the gas-liquid separation device (1). The heat exchange device comprises at least one coil-wound heat exchanger (4). The system has an increased depolymerization rate, and can extend an operating cycle of an apparatus.
