Phase equilibrium study of methane hydrate
… during dissociation was recorded with time. Equilibrium pressures were found to be 540 psi, 544 psi and 620 psi for 34°F, 36°F and 40°F, respectively. From the initial rate constants for formation, the activation energy was found to be 79 kJ/mole. The formation of hydrate usually …

Phase equilibrium studies at normal pressures
… has been developed to measure vapour-liquid equilibrium data on binary mixtures at atmospheric and sub-atmospheric pressures. The method gives isothermal data which can be obtained rapidly. Only measurements of total pressure are made as a direct function of composition of synthetic liquid …

Phase equilibrium studies at moderate pressures
… available, development of a recirculating equilibrium still based on a previously successful design (the modified Raal, Code and Best still of O'Donnell and Jenkins) is described. This novel still is designed to work at pressures up to 35 bar and for the measurement of both isothermal and …

Terfenol: a study of the phase equilibrium diagram and the solidification process
… Specific goals of this work were to verify the phase equilibria that is currently accepted for the systems DyFe{sub 2} and TbFe{sub 2}, and establish the phase equilibria near the composition Tb{sub 0.3}Dy{sub 0.7}Fe{sub 2}; establish that Terfenol grows directly from the liquid and that the …

Interval Methods for Reliable Computations of Phase Equilibrium From Equation of State Models
We have addressed the phase split problem with the Gibbs energy minimization approach. INTSTAB is first used to obtain all the stationary points. They provide extremely good initial estimates for the equilibrium phase compositions. An enhanced Han-Powell method for successive quadratic programming …

Phase equilibrium investigations of the Adirondack Class basalts from the Gusev plains, Gusev crater, Mars
Phase equilibrium experiments have been performed on a synthetic analog of the Gusev plains basalt composition from the Spirit landing site on Mars, determined by the Alpha Particle X-ray Spectrometer on the Spirit Rover (Gellert et al., 2006; McSween et al., 2006). The near-liquidus phase …
