In this work, the SAFT-VR Mie equation of state is used in conjunction with Dubinin-Radushkevich-Astakhov (DRA) and Steele potentials, according to Multicomponent Potential Theory Adsorption (MPTA), model thermodynamic behavior fluids confined porous media. The problem specifications are temperature, volume, number moles each component, yielding a Helmholtz energy-minimization problem. Calculat...

The vapor-liquid equilibrium of binary mixtures of xenon + SF6 has been measured at nine temperatures from 235.34 to 295.79 K and pressures up to 6.5 MPa. The mixture critical line is found to be continuous between the critical points of the pure components, and hence, the system can be classified as type I phase behavior in the scheme of van Konynenburg and Scott. The excess Gibbs free energie...

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...

An analytical equation of state by Song and Mason is developed to calculate the PVT properties ofmercury. The equation of state is based on the statistical-mechanical perturbation theory of hard convexbodies and can be written as a fifth-order polynomial in the density. There exists three temperaturedependentparameters in the equation of state; the second virial coefficient, an effective molecu...

supercritical carbon dioxide has gained increasing attention in food and pharmaceutical processing owing to the fact that it is environmentally inexpensive, not flammable, essentially non-toxic, and it has a convenient critical point. also, it has been attracting much attention in many fields, such as extraction of sensitive materials and pharmaceutical processing and polymerization processes. ...

In B-mode imaging, lateral resolution is impeded by the size and shape of the ultrasound beam used to create the image. For improved lateral resolution, a focussing method that utilises a beam model calculated using the Fraunhofer far field approximations to enhance the Synthetic Aperture Focussing Technique (SAFT) is proposed. The Beam Model Weighted Synthetic Aperture Focussing Technique (BMW...

The present work is the successful extension of an improved equation of state (EOS) to refrigerant fluids. The objective is the prediction of isothermal and saturated liquid densities of refrigerants. Two temperature-independent parameters appearing in the modified EOS are closely related to critical point properties of refrigerant fluids. Our results showed that, the proposed EOS can predict w...
