A heat integration method and system for a chemical recovery facility is provided that can reduce the carbon footprint and global warming potential of the facility. More particularly, one or more heat transfer media may be used to recover thermal energy from the waste plastic pyrolysis effluent, and to redistribute the recovered thermal energy throughout the chemical recovery facility. Thus, global warming potential for chemical recovery facilities may be optimized and reduced due to the heat integration methods and systems herein. 提供了一种用于化学回收设施的热集成方法和系统，其可以降低该设施的碳足迹和全球变暖潜在性。更特别地，一种或多种传热介质可以用于从废塑料热解流出物回收热能，并且将回收的热能重新分配到整个化学回收设施中。因此，由于本文的热集成方法和系统，化学回收设施的全球变暖潜在性可被优化和降低。
