Thermodynamic evaluation of PE/CO۲ system

In this work, the thermodynamic parameters of the PE/CO۲ system were investigated. Then, the effectof various factors like temperature and pressure on the thermodynamic parameters like solubility anddiffusivity was studied. Also, the solubility and diffusivity of CO۲ in sample were calculated by themagnetic suspension balance (MSB) system. The specific free volume of PE/CO۲ system wasdetermined by applying the PVT data and the equation of state, in which it was improved withincreasing of the temperature.
