摘要：
The solubility of CO(2) in aqueous blends of diethanolamine (DEA) and piperazine (PZ), from mixtures of CO(2) and N(2), was measured for temperatures and CO(2) partial pressures ranging from (303.14 to 353.14) K and (10.133 to 20.265) kPa, respectively. Measurements were made by a saturation method using a laboratory scale bubble column. The results of CO(2) solubility in liquid are expressed as alpha(CO2) (mol CO(2)/mol amine) for all experimental runs. A solubility model is developed to correlate and predict the solubility data Of CO(2) in aqueous blends of DEA and PZ. There is all acceptable degree of agreement between the experimental data of the present Study and predictions of the solubility model with an average absolute deviation of less than 4.5 %.
