There are many difficulties in the purification of raw components and products. However, researchers are seeking better ways for purification. One of the recent methods is extraction using supercritical fluids. In this study, the phase equilibria of benzoic acid -supercritical carbon dioxide system were investigated. Regarding the phase equilibria of this system, the modeling of solid-supercrit...

Hydrogen is a promising alternative to carbon based energy carriers and may be stored in large quantities subsurface storage deposits. This work assesses the impact of static (density phase equilibria) dynamic (viscosity diffusion coefficients) properties on pressure field during injection extraction hydrogen porous subsurface. In first step, we derive transport for water, their mixture using P...

An attempt is made in this work to combine the Lennard–Jones chain model (LJC) of self-diffusion coefficient with the statistical associating fluid theory (SAFT). The real non-spherical associating molecules are modeled as chains of tangent Lennard–Jones segments with association sites. An equation for the self-diffusion coefficient in a polyatomic associating fluid is presented as a product of...

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...
