New extensive data are reported for the solubility of carbon dioxide in fourteen physical solvents, and compared to two other solvents widely used in industry (selexol ® and sulfolane). The solubility data are expressed by Henry's law constants and have been measured at 25 °C, 40 °C and 60 °C, using an Autoclave cell. The study concludes that polyethylene glycol dimethyl ethers, and mixtures of these solvents are the best solvents for CO 2 removal.Les valeurs de la solubilité du dioxide de carbone dans quatorze solvants physiques sont reportées. Ces valeurs sont comparées avec la solubilté du dyoxide de carbone dans le sulfolane et le selexol ® . Les solubilités sont exprimées par les constantes de la loi d'Henry dans quatorze solvants et à des temperatures de 25 °C, 40 °C et 60 °C. L'étude conclue que les polyetylène-glycol dimetyleters et leurs mélanges sont les plus performants pour la décarbonatation du gaz.

Monte Carlo simulations are used to calculate the solubility of natural gas components in ionic liquids (ILs) and Selexol, which is a mixture of poly(ethylene glycol) dimethyl ethers. The solubility of the pure gases carbon dioxide (CO 2), methane (CH 4), ethane (C 2 H 6), and sulfur dioxide (SO 2) in the ILs 1-alkyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([C n mim][Tf 2 N], n = 4, 6), 1-ethyl-3-methylimidazolium diethylphosphate ([emim][dep]), and Selexol (CH 3 O[CH 2 CH 2 O] n CH 3 , n = 4, 6) have been computed at 313.15 K and several pressures. The gas solubility trend observed in the experiments and simulations is: SO 2 > CO 2 > C 2 H 6 > CH 4. Overall, the Monte Carlo simulation results are in quantitative agreement with existing experimental data. Molecular simulation is an excellent tool to predict gas solubilities in solvents and may be used as a screening tool to navigate through the large number of theoretically possible ILs.

Abstract. Biogas is a renewable energy source that has been developed recently. The main contents of Biogas itself are Methane and carbon dioxide (CO 2 ) where Methane is the main component of biogas with CO 2 as the highest impurities. The quality of biogas depends on the CO 2 content, the lower CO 2 levels, the higher biogas quality. Absorption is one of the methods to reduce CO 2 level. The selections of absorbent and appropriate operating parameters are important factors in the CO 2 absorption from biogas. This study aimed to find out the design parameters for CO 2 absorption using glycerol that represented by the overall mass transfer coefficient (K L a) and Henry's constant (H). This study was conducted in semi-batch bubble column. Mixed gas was contacted with glycerol in a bubble column. The concentration of CO 2 in the feed gas inlet and outlet columns were analysed by Gas Chromatograph. The variables observed in this study were superficial gas velocity and temperatures. The results showed that higher superficial gas velocity and lower temperature increased the rate of absorption process and the amount of CO 2 absorbed.
