摘要

摘要: 固定污染源是我国CO₂人为排放的主要来源，固定源碳减排是实现我国“双碳”目标的重要抓手。基于有机胺吸收法的碳捕集装置是目前使用最广泛的固定源CO₂排放控制技术，正在全球推广应用。有机胺及其降解产物随烟气的逃逸是该技术备受关注的问题，已有研究表明有机胺逃逸浓度可能高达十几~几十μg/m³，不仅造成碳捕集装置运行成本升高，对环境质量与人体健康也造成潜在影响。目前对固定源有机胺排放特征的认知相对匮乏，其主要原因之一是缺乏有机胺排放限值和监测技术规范，阻碍了对有机胺逃逸的深入认知与规范监管。梳理了当前针对固定源有机胺逃逸的监测方法，包括离线采样分析技术和傅里叶红外光谱、质子转移反应质谱等在线监测技术的基本原理和应用现状，结合当前监测需求讨论了各类技术在有机胺排放监测中的适用性，并对相关新型技术的后续发展进行了展望。

Abstract: Stationary sources are the major anthropogenic emitters of carbon dioxide in China， making carbon emission reduction from stationary sources a key strategy for achieving China’s Dual Carbon goals. Amine absorption-based carbon capture systems are currently the most widely used technology for CO₂ emissions control from stationary sources and are gradually promoted globally. The escape of amines and their degradation products with flue gas is a concern for this technology. Studies have shown that the concentration of escaped amine can reach levels as high as several tens μg/m³， which not only increases the operating cost of carbon capture systems but also poses potential risks to environmental quality and human health. At present， the understanding of amine emissions from stationary sources is still relatively limited. One of the main reasons is the lack of amine emission limit and monitoring technology specifications， which hinders in-depth understanding and regulatory oversight of amine escape. This paper reviews the current monitoring technologies for amine escape from stationary sources， including offline sampling and analysis technology， as well as online monitoring technologies such as Fourier Transform infrared spectroscopy （FTIR） and proton transfer reaction mass spectrometry （PTR-MS）， covering their basic principles and application status. We also discussed the applicability of these technologies in monitoring amine emissions in light of current monitoring needs and provided an outlook on future development of related novel technologies.
