활동도계수 모형을 고려한 아민수용액의 CO2 및 H2S 흡수 평형 계산 |
| 초록 |
In this study, the solubilities of CO2, H2S, and their mixtures have been measured and predicted from 40 to 130℃ by the static method. MDEA was chosen as most repsentative chemical solvent because it is thermodynamically and kinetically selective for H2S in the presence of CO2. Also Sulfolane was chosen as the physical solvent because of its stability and outstanding affinity. In order to overcome non-ideality, activity coefficients (liquid phase) and fugacity coefficients (vapor phase) were introduced. The activity coefficient models, such as Debye Huckel and Electrolyte NRTL models, take into account interaction between solute species in the liquid phase. Also, Kent Eisenburgh model without considering non-ideality (activity) was compared with both of two models. All the solubility calculations and optimizations (parameter estimations) were executed by using MATLAB® 2015b version. |
