Abstract In this study, new experimental data was obtained for the solubility and absorption rate of carbon dioxide in 2, 3 and 4 M of 4-Hydroxy-1-methylpiperidine (HMPD) aqueous solution and the effect of addition of 0.5 and 1.5 M aminoethylethanolamine (AEEA) on it. Experimental data was measured in a bath reactor within the temperature range of 303.15–373.15 K and pressure range of 28.3–1980.3 kPa. The solution viscosity was measured at different temperature and concentration conditions. Response surface methodology (RSM) was used for modeling and optimization of the CO2 loading and absorption rate. The results of RSM showed that AEEA concentration and partial pressure of CO2 have the maximum impact on absorption rate and CO2 loading, respectively. The maximum absorption rate and CO2 loading occurred at 2M HMPD+1.35M AEEA in 320.15K and 1980.3 kPa. The measured experimental values revealed that HMPD + AEEA solution has a more desirable absorption rate, CO2 loading and oxidative degradation in comparison to methylediethanolamine(MDEA) + piperazine(PZ) aqueous solution.

二氧化碳在 4-羟基-1-甲基哌啶 + 氨基乙基乙醇胺水溶液中的吸收性能：实验测量和建模

摘要 本研究获得了二氧化碳在 2、3 和 4 M 4-羟基-1-甲基哌啶 (HMPD) 水溶液中的溶解度和吸收率以及添加 0.5 和 1.5 M 氨基乙基乙醇胺的影响的新实验数据。 (AEEA) 就可以了。实验数据在浴反应器中测量，温度范围为 303.15-373.15 K，压力范围为 28.3-1980.3 kPa。在不同温度和浓度条件下测量溶液粘度。响应面方法 (RSM) 用于建模和优化 CO2 负载和吸收率。RSM 结果表明，AEEA 浓度和 CO2 分压分别对吸收率和 CO2 负荷影响最大。在 320.15K 和 1980 年，最大吸收率和 CO2 负荷出现在 2M HMPD+1.35M AEEA 时。3千帕。测量的实验值表明，与甲基二乙醇胺 (MDEA) + 哌嗪 (PZ) 水溶液相比，HMPD + AEEA 溶液具有更理想的吸收率、CO2 负载和氧化降解。
