China's aims of achieving CO emissions peak by 2030 and carbon neutrality by 2060 are crucial in guiding international efforts to mitigate climate change. Amine-based solvent technologies for capturing CO on a large scale have been implemented as retrofits in various industrial facilities, with a particular focus on coal-fired power plants. Nonetheless, its implementation within the waste-to-energy (WTE) industry is considerably limited and non-existent in China. This work presents a technical and economic evaluation of retrofitting a generic WTE facility in China with a carbon capture system. A rate-based process simulation model of the capture plant was developed in Aspen Plus, and the effect of equipment installation factors on capital cost was evaluated via the enhanced detailed factor (EDF) method. A set of key performance indicators were evaluated. The findings indicate that the energy demand linked to the capture system caused a decrease in efficiency by 13.17%, 14.85%, and 16.56% at 85%, 90%, and 95% capture rates, respectively, and the overall exergy efficiency of the system was reduced by 5.5%, 8.27%, and 10.63%, respectively. The estimated CO captured costs range from €56.41/tCO to €58.95/tCO, while CO avoided costs range from €153.33/tCO to €236.47/tCO. Retrofitting a CO capture unit at WTE facilities has the potential to substantially contribute to achieving the country's emission reduction targets. However, the successful implementation requires a comprehensive policy structure. This work offers some insights into the prospective integration of CO capture technology in China's WTE industry.
中国力争 2030 年前实现碳达峰、2060 年前实现碳中和的目标，对于引导国际社会共同应对气候变化具有重要意义。胺基溶剂捕集 CO2 技术已在各工业装置中作为 retrofit 技术得以应用，特别是在燃煤电厂中。然而，在中国，该技术在废物能源化（WTE）行业的应用相当有限，甚至尚未得到应用。本工作对中国某通用 WTE 设施进行 retrofit 碳捕集系统进行了技术和经济评估。在 Aspen Plus 中开发了捕集厂的速率基过程模拟模型，并通过增强详细因子（EDF）方法评估了设备安装因素对资本成本的影响。评估了一组关键性能指标。结果表明，捕集系统的能量需求导致效率分别下降了 13.17%、14.85%和 16.56%，在 85%、90%和 95%的捕集率下，系统的总㶲效率分别降低了 5.5%、8.27%和 10.63%。估计的 CO2 捕集成本范围为 56.41 欧元/tCO2 至 58.95 欧元/tCO2，而 CO2 避免成本范围为 153.33 欧元/tCO2 至 236.47 欧元/tCO2。在 WTE 设施中 retrofit CO2 捕集单元有潜力为实现国家减排目标做出重大贡献。然而，成功实施需要全面的政策框架。本工作为 CO2 捕集技术在中国 WTE 行业的潜在整合提供了一些见解。
