The Effect of Pure Component Characteristic Parameters on Sanchez-Lacombe Equation-of-State Predictive Capabilities

The dependence of predictive capabilities of SL EOS on the pure characteristic parameters of monomers and polymers is investigated. A sensitivity analysis study is carried out to understand the effect of these parameters on the predictive capability of SL EOS for different alpha-olefin/polyolefins systems. Among all pure component characteristic parameters, the monomer characteristic temperature (T-monomer*) has the largest impact on SL EOS predictive capability; whereas the polymer characteristic density (rho(polymer)*) is found to have the smallest impact.
