在本工作中，建立了一个简单易用的关联式，用于预测CO2在DEA和MDEA水溶液中的溶解度随还原分压和温度的变化。利用所生成的相互作用参数，将该模型应用于关联不同胺溶液中的CO2负荷。将关联式的结果与文献报道的实验数据进行了比较，发现在二乙醇胺(DEA)和甲基二乙醇胺(MDEA)的水溶液中，在较宽的操作条件下，观测数据与模型预测值之间有很好的一致性。
In the present work, a simple-to-use correlation is developed to predict the solubility of CO2 in aqueous solutions of DEA and MDEA as a function of the reduced partial pressure and temperature. Using the interaction parameters generated, the model is applied to correlate the CO2 loading in different amine solutions. The results from the proposed correlation have been compared with the reported experimental data and it was found that there is a good agreement between the observed data and the model predictions over a wide range of operating conditions in aqueous solutions of both diethanolamine (DEA) and methyldiethanolamine (MDEA).
