使用胺的燃烧后CO2捕获是最好理解的过程之一。用于此目的的最广泛使用和研究的溶剂是30%单乙醇胺（MEA）。该方法的主要问题是使用能量将CO2从溶剂中汽提出来。预计较高浓度的MEA可以捕获较高量的CO2，从而降低能耗，但也可能由于腐蚀和溶剂降解的潜在增加而导致环境排放的恶化。（与30% MEA相对）对捕获装置性能的影响，在英国碳捕集与封存研究中心（UKCCSRC）的中试规模先进捕集技术（PACT）设施中，使用30%和40%的MEA。吸收器（9 m高×0.3 m直径）采用28段（6.5 m）Mellapak CC 3规整填料。吸收柱温度曲线通过沿柱长沿着约48 cm安装的10个RTD测量。在不同的操作条件下，从再沸器负荷、捕集效率、负荷能力和液气比等方面对捕集装置的性能进行了评价，发现在相同的试验条件下，使用40%MEA的再沸器比负荷比使用30%MEA的再沸器比负荷下降了14%。还观察到，该工艺对再沸器温度非常敏感，再沸器温度的微小变化可对设备性能产生显著影响。此外，在再沸器/汽提器中的温度和压力的正确组合下，可以在不同的再沸器温度下实现类似的能量和捕获性能。发现40%MEA的腐蚀速率高于30%MEA。溶剂降解率和溶剂残留也表明略高，为40%。水洗显示出在从烟道气中回收大部分MEA方面是有效的。
Post combustion CO2capture using amines is one of the most well understood processes. The most widely used and studied solvent for this purpose is 30 % Monoethanolamine (MEA). The main issue with the process is the use of energy for stripping CO2out of the solvent. It is anticipated that higher concentrations of MEA can capture a higher amount of CO2and thus reduce energy consumption but may also result in a worsening of the environmental emissions due to potential increase in corrosion and solvent degradation.In order to study the impact of 40 % MEA (as opposed to 30 % MEA) on the capture plant performance, a test campaign was carried out at the Pilot Scale Advanced Capture Technology (PACT) facilities of the UK Carbon Capture and Storage Research Centre (UKCCSRC) using 30 % and 40 % MEA. The absorber (9 m height ×0.3 m dia.) is packed with 28 sections (6.5 m) of Mellapak CC3 structured packing. The absorption column temperature profile is measured by 10 RTDs installed around 48 cm apart along the column length. The performance of the capture plant in terms of reboiler duty, capture efficiency, loading capacity and liquid to gas ratio is evaluated at different operating conditions.It has been found that specific reboiler duty using 40 % MEA drops by up to 14 % as compared to that with 30 % MEA under similar test conditions. It has also been observed that the process is very sensitive to reboiler temperature and slight changes in reboiler temperature can have a significant impact on the plant performance. Moreover, similar energy and capture performance can be achieved at different reboiler temperatures with right combination of temperature and pressure in the reboiler/stripper. Corrosion rate was found to be higher with 40 % MEA than 30 % MEA. Solvent degradation rate and solvent carry over has also indicated slightly higher levels for 40 %. Water wash was shown to be effective in recovering most of the MEA from the flue gas.
