DEA复配水溶液二氧化碳溶解度的测定实验
Experimental study of the carbon dioxide absorption in mixtures of aqueous DEA and others
摘要
Abstract
A device was designed to measure the solubility of CO2 in the aqueous amine in this research. The following data were obtained, carbon dioxide solubility in 2 mol/L aqueous DEA at 308 K、318 K、 328 K、 358 K under CO2 partial pressure of 0—150 kPa. Meanwhile, mixtures of additives such as DETA, MDEA, AEE as well as SG and aqueous DEA were compounded and the solubility of CO2 in such mixtures were measured. The molar ratio of DEA and the additive in the mixture was 3 : 1 and the total concentration of the amine remained at 2 mol/L. The results showed that elevating the partial pressure of CO2 may contribute to the increase of the solubility in the aqueous DEA, and the temperature played a reverse role. Impacts of different additives on the solubility of CO2 was presented to be DETA > AEE > SG > MDEA.关键词
