Statistical associating fluid theory PC-SAFT

Perturbed Chain-Statistical Associating Fluid Theory (PC-SAFT)... [Pg.363]

The ability to model Selexol-based unit operations in Aspen Plus or Aspen HYSYS was recently made possible by the inclusion of the Perturbed-Chain Statistical Associating Fluid Theory (PC-SAFT) physical property model. As in Aspen HYSYS (see Section 6.1.1), a single chemical DEPG be used as a proxy for the mixture. Simple example files for using PC-SAFT with Selexol for one- or two-unit operations are included with the Aspen Plus distributiOTi, and an example for using PC-SAFT in Aspen HYSYS is available for download to subscribers of the Aspen Technology support website. [Pg.215]

Gonzalez et alP modeled the asphaltenes precipitation in live oils with the (Perturbed Chain-Statistical Associating Fluid Theory (PC-SAFT) see Chapter 8 for additional material. It is not an easy task to apply a complicated model such as PC-SAFT to systems consisting of a very large number of chemical... [Pg.283]

Simulation of polymerization and copolymerization kinetits requires additional information about the phase behavior of the monomer-polymer system. Cloud-point smdies oncopolymer-ethene as well as copolymer-ethene-comonomer systems have been carried out over wide p and T ranges under visual inspection of the reaction mbcmre. Part of the measured cloud-point curves have been modeled by permrbed chain -statistical associating fluid theory (PC-SAFT) theory. ... [Pg.890]

Experimental data including the acidic species in the vapor phase within the above concentration range are scarce. Only very few publications of VLE data in that range are available [168, 173]. In contrast, numerous vapor pressure curves are accessible in literature. Chemical equilibrium data for the polycondensation and dissociation reaction in that range (>100 wt%) are so far not published [148]. However, a starting point to describe the vapor-Uquid equilibrium at those high concentratirMis is given by an EOS which is based on the fundamentals of the perturbation theory of Barker [212, 213]. Built on this theory, Sadowski et al. [214] have developed the PC-SAFT (Perturbed Chain Statistical Associated Fluid Theory) equation of state. The PC-SAFT EOS and its derivatives offer the ability to be fuUy predictive in combination with quantum mechanically based estimated parameters [215] and can therefore be used for systems without or with very little experimental data. Nevertheless, a model validation should be undertaken. Cameretti et al. [216] adopted the PC-SAFT EOS for electrolyte systems (ePC-SAFT), but the quality for weak electrolytes as phosphoric... [Pg.407]
