摘要: Using simplified PC-SAFT we have modeled gas solubilities at high temperatures and pressures for the gases methane carbon dioxide in each of three polymers high-density polyethylene (HDPE), nylon polyamide-11 (PA-11), poly(vinylidene fluoride) (PVDF). In general results are satisfactory, using most cases a single, temperature-independent value binary interaction parameter. HDPE PVDF, temperature-dependent parameter was required. New pure component polymer parameters PA-11 PVDF were obtained recently developed prediction scheme which does not rely on experimental data.
