摘要：

The study of carbon dioxide (CO2) solubility in different solvents is important for the development of carbon capture and storage (CCS) technologies as well as for enhanced oil recovery (EOR) through CO2 injection. Using two different experimental methodologies, based on the synthetic method, the high-pressure solubilities of CO2 in four glymes, namely diethylene glycol methyl ether (DEGME), diethylene glycol dimethyl ether (DEGDME), diethylene glycol ethyl ether (DEGEE) and diethylene glycol diethyl ether (DEGDEE) were measured in a wide range of temperatures (293-353 K) and pressures up to 13 MPa. Furthermore, the experimental CO2 solubilities in the studied glymes were well described using the soft-SAFT EoS with parameters transferred from previous works, reinforcing its value as a reliable tool for the efficient simulation and design of new CCS/EOR technologies.
