HIx system thermodynamic model for hydrogen production by the sulfur-iodine cycle [PDF]
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]
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]
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

Modeling of Phase and Chemical Equilibria for Systems Involved in Biodiesel Production
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)

Transferability of data-driven, many-body models for CO2 simulations in the vapor and liquid phases
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 ...

Liquid—Vapor Equilibrium in the System Equilibrium Hydrogen—Helium [PDF]
Liquid—vapor equilibrium‐phase compositions for the binary system 20.40° equilibrium hydrogen—helium have been determined for six isotherms in the range 20.40°—31.50°K and at pressures up to 500 psia.
