二氧化碳技术中心（TCM DA）在胺基燃烧后二氧化碳捕获期间进行了广泛的大气排放监测。采用单乙醇胺水溶液（MEA）溶剂系统处理热电联产（CHP）电厂的烟气。发射监测采用傅里叶变换红外（FTIR）光谱分析仪、质子转移反应飞行时间质谱（PTR-TOF- MS）分析仪和人工等速采样，然后在实验室离线分析。在整个活动期间，大气中MEA的排放量非常低，从十亿分之几到百分之几（ppb, 1ppb = 10-9v/v）。大气中亚硝胺和硝胺等多边环境协定胺基降解产物的排放量低于可检测水平。大气中氨（NH3）的排放量处于低ppm范围。甲胺在低ppb范围内释放。发现吸收塔洗涤水段可以有效地减少胺基溶剂系统的大气排放。
Extensive atmospheric emission monitoring has been conducted at the CO2Technology Centre Mongstad (TCM DA) during amine based post-combustion CO2capture. The TCM DA amine plant was operated with an aqueous monoethanolamine (MEA) solvent system, treating flue gas from a combined heat and power (CHP) plant. Emission monitoring was conducted by a Fourier Transform Infrared (FTIR) Spectroscopy analyzer, a Proton Transfer Reaction Time-of-Flight Mass Spectrometry (PTR-TOF- MS) analyzer, and manual isokinetic sampling followed by off-line analysis in the laboratory.Atmospheric emissions of MEA were very low throughout the entire campaign, ranging from a few to a few hundred parts per billion (ppb, 1 ppb = 10-9v/v). Atmospheric emissions of MEA amine based degradation products such as nitrosamines and nitramines were below detectable levels. Atmospheric emissions of ammonia (NH3) were in the low ppm range. Methylamine was emitted at low ppb range.Absorber wash water sections were found to effectively reduce atmospheric emissions from amine based solvent system.
