New vapour liquid equilibrium (VLE) ebulliometric data for 2-Amino-2-methyl-1-propanol (AMP) and Piperazine (PZ) aqueous solutions are presented in this work for a range of temperatures, 30^◦C, 40^◦C and 50^◦C, and AMP:PZ molar ratios of 3:1.5/4:1/6:1 representative of those expected in water wash systems typically located at the top of absorber columns as an effective emission mitigation strategy in post-combustion carbon capture. The scatter in experimental data for AMP and PZ partial pressures suggests that obtaining VLE experimental data at low temperatures and low amine concentrations is challenging, despite its necessity. Experimental VLE data also suggest that an increase in the AMP/PZ ratio, as typically encountered in water wash processes, does not notably impact the volatility of each amine. The newly developed NRTL thermodynamic models in Aspen Plus (Yi et al. 2024) and Matlab (Hartono et al. 2021a) for the quaternary system AMP/Pz/H₂O/CO₂ show improvements in predicting the volatility of amines.

碳捕集应用在相关水洗条件下 AMP/PZ/H2O 系统的实验 VLE 数据


本研究提供了 2-氨基-2-甲基-1-丙醇 （AMP） 和哌嗪 （PZ） 水溶液的新蒸汽液体平衡 （VLE） 沸腾计量数据，适用于 30 ^◦ C、40 ^◦ C 和 50 ^◦ C 的温度范围，AMP：PZ 摩尔比为 3：1.5/4：1/6：1，代表了通常位于吸收柱顶部的水洗系统中的预期值，作为燃烧后碳捕获中的有效减排策略。AMP 和 PZ 分压实验数据中的分散性表明，尽管有必要，但在低温和低胺浓度下获得 VLE 实验数据具有挑战性。实验 VLE 数据还表明，水洗过程中通常遇到的 AMP/PZ 比值增加不会显著影响每种胺的挥发性。Aspen Plus（Yi 等人，2024 年）和 Matlab（Hartono 等人，2021 年）中针对四元系统 AMP/PZ/H ₂ O/CO ₂ 新开发的 NRTL 热力学模型在预测胺的挥发性方面显示出改进。
