in this work, the pc-saft equation of state (eos) has been used to model the solubility of acid gases (co2 and h2s) in two imidazolium-based ionic liquids (ils) ([c8-mim][pf6] and [c8-mim][tf2n]). parameters of pure ils were estimated using experimental densities. two strategies were considered to model densities of pure ils. in strategy 1, ils were modeled as nonassociating compounds and in st...

The spatial distribution of interactions in high energy collisions of heavy nuclei is discussed using the wounded nucleon, binary collision, hard sphere, and colliding disk parameterizations of interaction densities. The mean radius, its dispersion, and the eccentricity of the interaction region are calculated as a function of impact parameter. The eccentricity is of special interest for compar...

the extended hildebrand solubility parameter approach (ehsa) is used to estimate the solubility of satranidazole in binary solvent systems. the solubility of satranidazole in various water-peg 400 mixtures was analyzed in terms of solute-solvent interactions using a modified version of hildebrand-scatchard treatment for regular solutions. the solubility equation employs term interaction energy ...

Liquid-liquid equilibrium (LLE) problems such as phase stability analysis, phase equilibrium calculations, chemical equilibrium calculations, binary interaction parameter identification of thermodynamic models and other problems of fluid characterization have been the core subject of many recent studies. This study introduces Cuckoo Search (CS), Firefly Algorithms (FA) and its variants as p...

a method based on the genetic algorithm (ga) was developed to study the phase behavior of multicomponent and multiphase systems. upon application of the ga to the thermodynamic models which are commonly used to study the vle, vlle and lle phase equilibria, the physically meaningful values for the binary interaction parameters (bip) of the models were obtained. using the method proposed in this ...

the srk two-parameter cubic equation of state has been used for the calculation of the equilibrium constant using the liquid and vapor fugacity coefficients for three binary mixtures. dew and bubble points have been determined using the equilibrium constants and the phase envelope has been plotted showing dearly that retrograde condenstaion occurs. the following percent deviations have been obt...

In this work, the PC-SAFT equation of state (EoS) has been used to model the solubility of acid gases (CO2 and H2S) in two imidazolium-based ionic liquids (ILs) ([C8-mim][PF6] and [C8-mim][Tf2N]). Parameters of pure ILs were estimated using experimental densities. Two strategies were considered to model densities of pure ILs. In strategy 1, ILs were modeled as nonassociating compounds and in st...
