摘要: The knowledge of solubility gases and hydrocarbons in polymer has enormous importance the design development reactor, foaming, membrane separation processes. In this work, polyethylene was correlated using a thermodynamic model based on perturbed-chain statistical associating fluid theory (PC-SAFT). experimental data various such as ethylene, carbon dioxide, nitrogen, methane, up to chain length seven both molten semicrystalline been reviewed suitability developed PC-SAFT then tested available literatures for hydrocarbons. Furthermore, optimum values adjustable solvents-solute binary interaction parameters (Kij) at different temperatures have estimated by regression isotherms. A suitable correlation Kij with temperature temperatures. calculated from compared results reasonably good observed
