摘要：Ethylene production is an energy-intensive process with significant CO2 emissions. As demand for ethylene rises, integrating carbon capture technology in ethylene plants is crucial for mitigating emissions. This study provides a thermodynamic, exergy, comparative life cycle assessment (LCA) and economic analysis of post-combustion carbon capture (PCC) for large-scale ethylene plants using chemical absorption with 30 wt% monoethanolamine (MEA) and 40 wt% piperazine (PZ) as solvent. In addition, a case study involving the integration of solarassisted post-combustion carbon capture (SPCC) and photovoltaic (PV) power generation with ethylene production is built to evaluate future CO2 emission reduction potential. The results show that 0.98 tons of CO2 are captured per ton of ethylene, potentially reducing life cycle CO2 emissions by 30.3% to 68.9% for different PCC scenarios. Integrating SPCC and PV significantly reduces CO2 emissions, highlighting the potential of solar power in carbon reduction. Furthermore, feedstock acquisition of ethylene production emits large amount of greenhouse gas (GHG), indicating that low-carbon feedstock production can further reduce life cycle GHG emissions. This work is significant for the ethylene industry's low-carbon transition and clean production, offering insights into enhancing sustainability and environmental performance through advanced carbon capture technologies and renewable energy integration.
