二氧化碳在单乙醇胺水溶液中的溶解度已由几位研究者进行了测定。Mason和Dodge(4)研究了二氧化碳在0.5、2.0、5.0、9.5和12.5N溶液中的溶解度，这些溶液的温度分别为0、25、50和75℃，二氧化碳的部分压力约为20到750 mm。Reed和Wood(7)发表了一个小规模的曲线图，显示了二氧化碳在2.51V(15.3重量%)的MEA溶液中的溶解度，温度为100、120和140摄氏度，二氧化碳分压为20到250 PSIA。这些作者并不声称他们的测量精度很高。Reed(6)给出了类似的数据。Lyudkovskaya和Lei-Bush(3)研究了二氧化碳在25、50和75摄氏度、二氧化碳分压从2.5到40大气压下在0.5、2和5N的MEA溶液中的溶解度。Muhlbauer和Monaghan(5)最近报告了二氧化碳在25℃和100℃、分压约为1到1000毫米的2.5A‘MEA溶液中的溶解度数据。Riegger、Tartar和Lingafelter(8)测量了硫化氢在0.6、1.0、1.5、2.0、3.0和5.0摩尔的MEA溶液中的溶解度，温度为25、45和60℃，硫化氢的分压为25-700 mm。LeiBush和Shneerson(2)报道了硫化氢在0.93和2.51V的MEA溶液中的溶解度，温度分别为15、25和50℃，分压范围约为0.01-250 mm。Reed(6)包括一个显示硫化氢在100和120摄氏度下的溶解度的小规模曲线图，实验点覆盖了大约22到53 PSIA Muhlbauer的分压范围，Monaghan(5)报告了在25和100“C的分压，分压约为1到950毫米。Atwood、Arnold和Kindrick(1)计算了硫化氢-MEA-水体系的活度系数。LeiBush和Shneerson(2)已经获得了25℃下二氧化碳和硫化氢混合物在15.3重量%的甲基乙酸乙酯中的溶解度的有限数据。在他们的实验中，硫化氢浓度保持在每摩尔胺0.145或0.265摩尔不变，而二氧化碳浓度在每摩尔胺0.025至0.416摩尔之间变化。Muhlbauer和Monaghan(5)发表了在25℃和100℃下，硫化氢和二氧化碳在15.3重量%乙二醇胺中的同时溶解度的数据。他们的数据是在硫化氢分压为1-964 mm时获得的。二氧化碳压力从1毫米到1290毫米。报道的硫化氢和二氧化碳的溶解度有很大的不同。在低分压、高温区的数据非常贫乏。关于这两种酸性气体混合物的数据也受到覆盖范围和温度范围的限制。
Determinations of the solubility of carbon dioxide in aque-ous monoethanolamine solutions, have been made by several investigators. Mason and Dodge (4) studied the solubility of carbon dioxide in 0.5, 2.0, 5.0, 9.5, and 12.5 N solutions at temperatures of 0, 25, 50, and 75 C. and at partial pres-sures of carbon dioxide ranging from about 20 to 750 mm. Reed and Wood (7) published a small-scale plot showing the solubility of carbon dioxide in 2.51 V (15.3 weight%) MEA solutions at temperatures of 100, 120, and 140 C., and carbon dioxide partial pressures from 20to 250 psia These authors did not claim high accuracy for their measurements. Similar data are given by Reed (6). Lyudkovskaya and Lei-bush (3) studied the solubility of carbon dioxide in 0.5, 2, and 5N MEA solutions at temperatures of 25, 50, and 75 C. and carbon dioxide partial pressures from 2.5 to 40 atm. Muhlbauer and Monaghan (5) recently reported data on the solubility of carbon dioxide in 2.5 A'MEA solutions at 25 and 100 C. and partial pressures of about 1 to 1000 mm. Riegger, Tartar, and Lingafelter (8) measured the solu-bility of hydrogen sulfide in 0.6, 1.0, 1.5, 2.0, 3.0, and 5.0 molal solutions of MEA at temperatures of 25, 45, and 60 C. and at partial pressures of hydrogen sulfide from 25 to 700 mm. Leibush and Shneerson (2) reported the solubil-ity of hydrogen sulfide in 0.93 and 2.51 V solutions of MEA at temperatures of 15, 25, and 50 C. and over a partial pressure range of about 0.01 to 250 mm. Reed (6) included a small-scale plot showing the solubility of hydrogen sulfide at 100 and 120 C., with experimental points covering a partial pressure range of about 22 to 53 psia Muhlbauer and Monaghan (5) reported values at 25 and 100 “C. for partial pressures of about 1 to 950 mm. Atwood, Arnold, and Kindrick (1) computed activity coefficients for the system hydrogen sulfide-MEA-water. Limited data at 25 C. on the solubility of mixtures of carbon dioxide and hydrogen sulfide in 15.3 weight% MEA have been obtained by Leibush and Shneerson (2). In their experiment, the hydrogen sulfide concentration was held constant at either 0.145 or 0.265 mole per mole of amine while the carbon dioxide con-centration was varied from 0.025 to 0.416 mole per mole of amine. Muhlbauer and Monaghan (5) published data on the simultaneous solubility of hydrogen sulfide and carbon dioxide in 15.3 weight% MEA at temperatures of 25 and 100 C. Their data were obtained at hydrogen sulfide par-tial pressures ranging from 1 to 964 mm. and at carbon dioxide pressures from 1 to 1290 mm. There are considerable differences in the reported values for the solubilities of hydrogen sulfide and carbon dioxide. Data in the low partial pressure, high temperature region are very meager. The data on mixtures of the two acidic gases are also limited in scope and temperature range cov-ered.
