The solubility of two single gases carbon dioxide and hydrogen sulfide are studied in the ionic liquid 1- ethyl-3-methylimidazolium ethylsulfate ([emim][EtSO4]) at temperatures ranging from(303.15 to 353.15)K and pressures up to 1.6Mpa. A thermodynamic model based on the Modified Peng-Robinson equation of state with the Wong-Sandler mixing rule using the UNIQUAC-NRF activity coefficient model is applied. The results show that the present model gives good results so that the calculated data are in good agreement with the experiment
