In this work, the solubility of CO₂ in aqueous methyldiethanolamine (MDEA) + bis-(2-hydroxyethyl) methylammonium formate (BHEMAF) system was measured using the static method at two temperatures (298.15 and 313.15 K) in the pressure range of 100–2100 kPa. Two sets of experiments were performed. In the first set, the weight percentage of BHEMAF, MDEA and H₂O in H₂O + MDEA + BHEMAF solutions were 7.5–10 wt%, 15–39.38 wt% and 53.12–75 wt%, respectively. In the second set of experiments concentration of BHEMAF was set as 0.3 and 0.6 M in the aqueous solutions of 25 wt% MDEA. Experimental data showed that the solubility of CO₂ in the H₂O + MDEA + BHEMAF solutions decreases with increasing BHEMAF concentration. The Deshmukh-Mather thermodynamic model was then used to calculate the solubility of CO₂ in H₂O + MDEA + BHEMAF solutions. The binary interaction parameters of the model were adjusted by regression to experimental data. The modeling results showed that the average absolute relative percent deviation for all the data points was 7.87%.

在这项工作中，使用静态方法在两个温度（298.15和313.15 K），压力范围为100的条件下，测量了CO ₂在甲基二乙醇胺（MDEA）+双-（2-羟乙基）甲基甲酸铵（BHEMAF）体系中的溶解度。 –2100 kPa。进行了两组实验。在第一组中，H ₂ O + MDEA + BHEMAF溶液中BHEMAF，MDEA和H ₂ O的重量百分比分别为7.5–10 wt％，15–39.38 wt％和53.12–75 wt％。在第二组实验中，在25 wt％MDEA的水溶液中，BHEMAF的浓度设置为0.3和0.6M。实验数据表明，CO ₂在H ₂中的溶解度O + MDEA + BHEMAF溶液随着BHEMAF浓度的增加而降低。然后使用Deshmukh-Mather热力学模型计算CO ₂在H ₂ O + MDEA + BHEMAF溶液中的溶解度。通过回归到实验数据来调整模型的二元相互作用参数。建模结果表明，所有数据点的平均绝对相对偏差百分比为7.87％。
