The compounds CO2 and H2S are acid gases (AG) known to negatively affect the environment due to their corrosion potential. As a solution, amine solvents are used to absorb such gases and each of them has different physicochemical properties because of their molecular structures. In the absence of a complete structures and properties information, group contribution thermodynamic methods are applied. Therefore, this research aims to compare physicochemical properties of the methods proposed by
