The perturbed chain-statistical associating fluid theory (PC-SAFT) equation of state (EoS) is applied, and its performance assessed using a reliable free-to-access benchmark thermodynamic database developed by the authors. A total 200 non-electrolytic binary systems are included in database, which divided into nine groups according to character components, that is, their ability be involved hyd...

Ž . In this work, we apply the Gibbs–Duhem integration GDI technique to obtain the vapor–liquid equilibrium Ž . VLE properties of hydrogen fluoride according to three potential models. Properties examined include coexistence densities, enthalpy of vaporization, and vapor pressure. The models are representative of the various types of potentials used in simulation studies; namely, a pure pair po...

The perturbed-chain statistical associating fluid theory (PC-SAFT) density functional theory developed in our previous work was extended to the description of inhomogeneous confined behavior in nanopores for mixtures. In the developed model, the modified fundamental measure theory and the weighted density approximation were used to represent the hard-sphere and dispersion free energy functional...

In a recent paper we predicted the fluid-phase equilibria of n-butane + n-alkane binary mixtures using the statistical associating fluid theory for chain molecules with attractive potentials of variable range (SAFTVR). Now we focus on the methane + n-hexane system, again using the SAFT-VR approach. The methane + n-hexane system exhibits type V phase behavior, in which partial miscibility of the...

Classical and nonclassical calculations of nucleation rates are presented for methanol, an associating vapor system. The calculations use an equation of state (EOS) that accounts for the effects of molecular association based on the statistical association fluid theory (SAFT). Two forms of classical nucleation theory (CNT) were studied: a Gibbsian form known as the P-form and the standard or S-...

Multi-element ultrasonic transducer arrays open the possibility for rapid and flexible tomographic imaging systems. By electronic switching of the individual array elements, different schemes of reflection tomography and transmission tomography can be realized. This contribution firstly introduces general tomographic measurement principles to some detail. It then describes two multi-channel low...

Small changes in temperature or pressure can lead to crude oil phase separation and multiple orders of magnitude change viscosity. The one-parameter friction theory framework using the SARA-based method with perturbed-chain statistical association fluid (PC-SAFT) EoS has proven have high accuracy viscosity predictions light oil. However, it failed for heavy In this work, above model is modified...

A mathematical model for polymerization kinetics and molar mass development in the nitroxide-mediated (NMP) of vinyl monomers supercritical carbon dioxide (scCO2) has been developed. The method moments is used development. perturbed-chain statistical associating fluid theory (PC-SAFT) equation state to estimate number stable phases present at equilibrium reaction mixture, critical average chain...
