Vapor-liquid equilibrium relationships are important properties for practical use, such as in the design and operation of distillation equipment. In general, vapor-liquid equilibrium relations are determined experimentally, and it is a custom to test the thermodynamic consistency of the equilibrium data. Investigators1^4-15'17'19~22-24) have proposed various methods for testing thermodynamic co...

Thermodynamic consistency test of isothermal vapor-liquid equilibrium (VLE) data of various binary systems containing Carbon dioxide (CO2)/Room temperature ionic liquids (RTILs) have been investigated in wide ranges of pressures in each isotherm precisely. In this paper Generic van der Waals (GvdW) equation of state (EoS) coupled with modified van der Waals Berthelot mixing rule has ...

Abstract: A thermodynamic consistency test developed for high pressure binary vapor-liquid mixtures is applied to mixtures containing a supercritical solvent and an ionic liquid. Several authors have reported vapor-liquid equilibrium data on the binary systems supercritical CO2 + 1-butyl-3-methyl imidazolium hexafluorophosphate {[bmim][PF6]}, supercritical CO2 + 1-butyl-3-methyl imidazolium nit...

Starting from a microscopic system-baths description, we derive the general conditions for time-local quantum master equation (QME) to satisfy first and second law of thermodynamics at fluctuating level. Using counting statistics, show that can be rephrased as Generalized Quantum Detailed Balance condition (GQDB), i.e., symmetry generators which ensures validity fluctuation theorem. When requir...
