Abstract With current environmental regulations, CO2 capture is very crucial for the survival of coal-fired power plants in the near future. In this work, the CO2 absorption performances of Na2CO3, NaOH, Monoethanolamine (MEA) and frother-enhanced Na2CO3 were investigated experimentally in a pilot scale gas−liquid countercurrent column. A surfactant was added to the sodium carbonate solution in order to increase the surface area available for CO2 transport within the packed bed. This increased the CO2 capture efficiency of dilute sodium carbonate slurry from 55.6% to 99.9%, before reaching saturation. The main intent of this study is to compare the efficiency of frothers and conventional reagents for chemical absorption CO2 capture. We analyzed the advantages and disadvantages of each of these reagents along with frother-enhanced sodium carbonate slurry.

使用起泡剂提高稀碳酸钠浆液的吸收效率，用于燃烧后的 CO2 捕集

摘要 根据当前的环境法规，CO2 捕集对于燃煤电厂在不久的将来的生存至关重要。在这项工作中，在中试规模的气液逆流塔中，对 Na2CO3、NaOH、单乙醇胺 (MEA) 和泡沫增强的 Na2CO3 的 CO2 吸收性能进行了实验研究。将表面活性剂添加到碳酸钠溶液中以增加填充床内可用于 CO2 传输的表面积。这将稀释碳酸钠浆液的 CO2 捕获效率从 55.6% 提高到 99.9%，然后达到饱和。本研究的主要目的是比较起泡剂和传统试剂在化学吸收 CO2 捕获方面的效率。
