This paper presents multicriteria environmental and economic analyses of municipal solid waste (MSW) grate incineration power plants without and with CO₂ capture and separation (CCS) technologies, including monoethanolamine (MEA) absorption, pressure/vacuum swing adsorption (P/VSA), and oxy-fuel combustion (Oxy). The life-cycle analysis (LCA) and techno-economic analysis (TEA) are integrated with the analytic hierarchy process (AHP) and technique for order preference by similarity to ideal solution (TOPSIS) approaches for systematic environmental and economic analysis. This systematic methodology is applied to investigate the applicability of CCS technologies in MSW incineration power plants from perspectives of local government, enterprise, residents, and “equal” weight. The results show that application of CCS reduces the ecosystem quality and the human health impacts, but increases the resource use and yields an economic penalty of from ∼$33.45 to ∼$45.98 per ton of CO₂ avoidance. From the perspective of residents only, the MSW incineration power plant with CCS performs better than that without CCS. The promotion in energy efficiency and carbon price are the critical factors for CCS to attract the support from government and enterprise, respectively. In terms of the three CCS technologies, P/VSA and Oxy have similar comprehensive performances, better than MEA absorption.

生命周期视角下含碳捕集与分离的城市生活垃圾焚烧发电厂的多标准环境经济分析

本文介绍了不使用CO ₂和使用CO ₂的城市固体垃圾（MSW）炉排焚烧发电厂的多标准环境和经济分析捕集与分离（CCS）技术，包括单乙醇胺（MEA）吸收，压力/真空变压吸附（P / VSA）和含氧燃料燃烧（Oxy）。生命周期分析（LCA）和技术经济分析（TEA）与层次分析法（AHP）和技术相集成，从而通过类似于理想解决方案（TOPSIS）的方法进行系统环境和经济分析。从地方政府，企业，居民和“等量”的角度出发，采用这种系统的方法论来研究CCS技术在垃圾焚烧发电厂中的适用性。结果表明，CCS的应用降低了生态系统质量和对人类健康的影响，但增加了资源利用，并产生了每吨CO ₂约33.45美元至约45.98美元的经济损失。回避。仅从居民的角度来看，装有CCS的城市垃圾焚烧发电厂的性能要优于没有CCS的城市。能源效率和碳价的提高是CCS分别吸引政府和企业支持的关键因素。就三种CCS技术而言，P / VSA和Oxy具有相似的综合性能，优于MEA吸收。
