The use of amine scrubbing methods for reducing CO₂ emission from burning fossil fuels is growing in popularity. A major challenge of carbon capture methods using amines is high energy consumption. Moreover, the emission of amines from the carbon capture plant gains increasing attention due to environmental concerns. The amines may evaporate from the solution or be released in the form of an aerosol and enter the atmosphere.

In order to determine the amines emission, experimental research was conducted using a process development unit. The composition of the gases from the absorber and desorber were measured using a Fourier Transform Infrared (FTIR) gas analyser. A solvent blend of 2-amino-2-methyl-1-propanol (AMP) and piperazine was utilised. Synthetic flue gas containing 12.7–12.9 % vol. (dry basis) of CO₂ was directed to the absorber with a flow rate of 100 m³/h. Fresh water was supplied to the top of the absorber to maintain the water balance. No other form of water wash was used.

The major components that were emitted together with the treated gas were ammonia and AMP. The produced CO₂ contained traces of amine, ammonia and formic acid. The concentration of other degradation products was below the limit of quantification. Increasing the lean solvent temperature by 15 °C resulted in an increase in AMP emission by over 50 ppm. By analysing the vapour pressure literature data with obtained results, the emission was considered mainly as vapour-based. Water dosing at the top of the absorber proved to be effective in reducing amine emissions.

为了减少燃烧化石燃料引起的CO ₂排放，使用胺洗涤方法变得越来越流行。使用胺的碳捕获方法的主要挑战是高能耗。此外，由于对环境的关注，碳捕集装置中胺的排放受到越来越多的关注。胺可从溶液中蒸发或以气溶胶形式释放并进入大气。

为了确定胺的排放，使用过程开发单元进行了实验研究。使用傅立叶变换红外（FTIR）气体分析仪测量来自吸收器和解吸器的气体组成。使用2-氨基-2-甲基-1-丙醇（AMP）和哌嗪的溶剂混合物。合成烟气的体积含量为12.7-12.9％。将CO ₂（干基）以100 m ³ / h的流量导入吸收器。将淡水供应到吸收塔的顶部，以保持水平衡。没有使用其他形式的水洗。

与已处理气体一起排放的主要成分是氨和AMP。产生的CO ₂含有痕量的胺，氨和甲酸。其他降解产物的浓度低于定量极限。将稀溶剂温度提高15°C，可使AMP排放增加50 ppm以上。通过分析蒸气压文献数据并获得结果，排放主要被认为是基于蒸气的。事实证明，在吸收塔顶部加水可有效减少胺的排放。
