Vle have developed a predictive corresponding states model for the thermo· physical properties of pure refrigerants and refrigerant mixtures. The bulk phase properties such as the density, enthalpy and entropy are predicted using the prin· ciple of extended corresponding states. This theoretically based model uses shape factors to insure conformality among the various components and R134a is us...

Isobaric vapor-liquid equilibrium measurements are reported for the binary mixture of Methyl acetate and Isopropylbenzene at 97.3 kPa. The measurements have been performed using a vapor recirculating type (modified Othmer's) equilibrium still. The mixture shows positive deviation from ideality and does not form an azeotrope. The activity coefficients have been calculated taking into considerati...

The knowledge of the phase equilibrium refrigerant mixtures is crucial for optimization production processes molecules, and design energetic systems (heat pumps, Organic Rankine Cycles, …). In this work, different predictive thermodynamic models (COSMO-RS COSMO-SAC-dsp) have been used to determine behavior refrigerants involving alkanes, fluorinated chlorinated compounds. COSMO-RS model leads r...

Hydrogen (H2) has emerged as a viable solution for energy storage of renewable sources, supplying off-seasonal demand. contamination due to undesired mixing with other fluids during operations is significant problem. Water regular occurrence; therefore, an accurate prediction H2-water thermodynamics crucial the design efficient and water removal processes. In thermodynamic modeling, Peng–Robins...
