A method and system for recovering the recovery component carbon dioxide is provided that can reduce the carbon footprint and global warming potential of a chemical recovery facility. More particularly, pyrolysis flue gas and/or pyrolysis gas from pyrolysis of waste plastic may be processed in an absorption system to form a recovered CO2 stream comprising the recovered component carbon dioxide. Thus, the global warming potential of the chemical recovery facility can be optimized and reduced due to the carbon dioxide recovery methods and systems herein. 提供了一种用于回收回收成分二氧化碳的方法和系统，其可以降低化学回收设施的碳足迹和全球变暖潜势。更特别地，来自废塑料热解的热解烟道气和/或热解气可以在吸收系统中处理，从而形成包含回收成分二氧化碳的回收的CO2流。因此，由于本文的二氧化碳回收方法和系统，化学回收设施的全球变暖潜势可被优化和降低。
