Solvent emissions is a serious problem in the industrialization of the amine scrubbing process. To design pollutant control equipment for a 2 million tons/year CO₂ capture plant, a bench and a pilot facility were tested to investigate the aerosol emissions. And three Aspen models were built to study vapor emission and design emissions control measurement. The emissions assessment showed the treated flue gas after the absorber was about to discharge 1078 mg/Nm³ aerosol-type solvent and 1055 mg/Nm³ vapor-type solvent. The experimental results of particle size distribution indicated that improving the growth of the submicron droplets before the water wash and demister was the key to control aerosol emissions. Three control methods were compared by simulation, the best control measure was the combination of dry bed and water wash section, and the drain-out water is feed to the top of the dry bed. Considering the economy and control efficiency, the packing height of the water wash section is 2.5 m, and the scrubbing flow rate is 5000 Nm³/h. The extra cooling for the dry bed is not necessary and uneconomic. Under this countermeasure, the vapor emissions solvent is as low as 1.27 mg/Nm³ without additional freshwater for the water wash section.

溶剂排放是胺洗涤工艺工业化过程中的一个严重问题。为了设计一个 200 万吨/年的 CO ₂捕集厂的污染物控制设备，测试了一个工作台和一个中试设施来调查气溶胶排放。并且建立了三个 Aspen 模型来研究蒸汽排放和设计排放控制测量。排放评估显示，吸收塔处理后的烟气即将排放1078 mg/Nm ³气溶胶型溶剂和1055 mg/Nm ³蒸气型溶剂。粒径分布的实验结果表明，在水洗除雾器之前改善亚微米液滴的生长是控制气溶胶排放的关键。通过模拟对三种控制方式进行了比较，最佳控制措施为干床与水洗段相结合，排出的水从干床顶部进料。考虑到经济性和控制效率，水洗段填料高度为2.5 m，洗涤流速为5000 Nm ³ /h。干床的额外冷却是不必要的，也是不经济的。在此对策下，蒸汽排放溶剂低至 1.27 mg/Nm ^{3 ，}无需额外的淡水用于水洗部分。
