HIx system thermodynamic model for hydrogen production by the sulfur-iodine cycle [PDF]
, 2009 The HIx ternary system (H2O – HI – I2) is the latent source of hydrogen for the Sulfur – Iodine thermo-chemical cycle. After analysis of the literature data and models, a homogeneous approach with the Peng-Robinson equation of state used for both the ...

Modelling of a dynamic multiphase flash: the positive flash. Application to the calculation of ternary diagrams [PDF]
, 2004 A general and polyvalent model for the dynamic simulation of a vapor, liquid, liquid-liquid, vapor-liquid or vapor-liquid-liquid stage is proposed. This model is based on the -method introduced as a minimization problem by Han & Rangaiah (1998) for ...

The Convective Instabilities in a Liquid-Vapor System with a Non-equilibrium Evaporation Interface [PDF]
, 2009 Rayleigh-Marangoni-B,nard instability in a system consisting of a horizontal liquid layer and its own vapor has been investigated. The two layers are separated by a deformable evaporation interface. A linear stability analysis is carried out to study the

Transferability of data-driven, many-body models for CO2 simulations in the vapor and liquid phases [PDF]
, 2021 Extending on previous work by Riera et al. [J. Chem. Theory Comput. 16, 2246 (2020)], we introduce a second generation family of data-driven many-body MB-nrg models for CO2 and systematically assess how the strength and anisotropy of the CO2-CO2 ...

Modeling of Phase and Chemical Equilibria for Systems Involved in Biodiesel Production
Chemical Engineering Transactions, 2015 In recent years, the interest in the use of renewable energy has encouraged the growth of studies into renewable sources, such as the production of biofuels. This work investigates the vapor-liquid equilibrium (VLE), vapor-liquid-liquid equilibrium (VLLE)

Isobaric vapor–liquid and vapor–liquid–liquid equilibrium data for the water–ethanol–hexane system [PDF]
, 2006 Isobaric vapor–liquid and vapor–liquid–liquid equilibria were measured for the water–ethanol–hexane system at normal atmospheric pressure. The apparatus used for the determination of vapor–liquid–liquid equilibrium data was an all-glass dynamic ...

Vapor-liquid equilibrium of acid gases with imidazolium-based ionic liquids using the UMR-PRU model
Chemical Thermodynamics and Thermal Analysis, 2022 The UMR-PRU group contribution equation of state (EoS), which couples the Peng-Robinson EoS with UNIFAC via the Universal Mixing Rules, is extended to pure imidazolium-based ionic liquids (ILs), as well as to their mixtures with CO2 and H2S.
