A thermodynamic model based on the Perturbed-Chain Statistical Associating Fluid Theory (PC-SAFT) equation of state has been developed for correlating experimental data. The model is able to predict the composition of the liquid phase with an average deviation of 8.0%. However, the model does not calculate correctly the concentration of PEG in the gas phase. The model is also capable of predicting VLE data reported in the literature of PEG + CO2 mixtures with PEGs of molecular weights ranging from 1500 g/mol to 18500 g/mol as well as solid-fluid equilibrium of carbon dioxide + PEG mixtures at pressures below 10 MPa.ensupercritical carbon dioxideparticles from gas saturated solutionsperturbed-chain statistical associating fluid theorydryingmodellingüberkritisches KohlendioxidHochdrucksprühverfahrenTrocknungModellierung620541journal article
