Abstract
In this work, the reliability of PC-SAFT equation of state developed by Sadowski et al., Ind. Eng. Chem. Res. 40 (2001) 1244 has been evaluated in prediction of vapor-liquid equilibria (VLE) for solvent + anti solvent CO2 systems. The systems studied were divided into four categories, there were CO2 + hidrocarbon normal alkane, CO2 + hidrocarbon cyclic, CO2 + hidrocarbon aromatic, and CO2 + hidrocarbon ketone systems. The results show that PC-SAFT equation of state is capable of predicting VLE accurately for all categories of the systems with overall average absolute deviation of 2.4 %. The performance of PC-SAFT was found to be better than Peng-Robinson equation of states. In addition, the VLE behavior of those systems obtained in this work is necessary to be applied for designing and optimizing production of nano and micro particle in supercritical anti-solvent process.
