Abstract

This study presents experimental and modeling data of solubility of carbon dioxide (CO2) in aqueous solutions that contain water-soluble additives. Low concentration of tetrahydrofuran (THF) and sodium dodecyl sulfate (SDS), which are very commonly used additives in the field of clathrate hydrates research, have been considered here. A simple experimental method is proposed to determine the gas solubility. The measured data, in good agreement with those found in literature, allow developing a straightforward thermodynamic model and an easy-to-use engineering correlation for the determination of the apparent Henry constant, used to estimate the CO2 solubility in aqueous solutions containing SDS, at different temperatures and THF concentrations. Finally, as a practical application, experimental data and modeling results are compared regarding the equilibrium pressure and the gas composition obtained after solubilization of a typical CO2−CH4 gas mixture.
