Volumetric behaviour of (carbon dioxide + hydrocarbon) mixtures at high pressures
Johnny Zambrano, Franklin V. Gómez-Soto, Daniel Lozano-MartÃn +2
The interest of oil industry in increasing heavy oil production has promoted the use of enhanced oil recovery techniques such as injection, which produce a decrease of oil…
Speeds of sound for a biogas mixture + + + from = (1-12) MPa at = (273, 300 and 325) K measured with a spherical resonator
Daniel Lozano-MartÃn, José J. Segovia, M. Carmen MartÃn +2
The present work aims to measure speeds of sound in a biogas mixture of + + + , at = (1-12) MPa and = (273, 300 and 325) K, using a spheri…
Updated determination of the molar gas constant by acoustic measurements in argon at UVa-CEM
J J Segovia, D Lozano-MartÃn, M C MartÃn +5
A new determination of the molar gas constant was performed from measurements of the speed of sound in argon at the triple point of water and extrapolation to zero pressure. A new…
A novel technique based on a cylindrical microwave resonator for high pressure phase equilibrium determination
Rodrigo Susial, Ãngel Gómez-Hernández, Daniel Lozano-MartÃn +3
The development of a novel technique based on a cylindrical microwave resonator for high pressure phase equilibrium determination is described. Electric permittivity or dielectric…
Speeds of sound for ( + ) mixtures from = (0.5 to 20) MPa at = (273.16 to 375) K
Daniel Lozano-MartÃn, Andres Rojo, M. Carmen MartÃn +2
This work aims to provide accurate and wide-ranging experimental new speed of sound data (,) of two binary ( + ) mixtures at a nominal helium content of 5% and…
Determination of the force transmission error in a single-sinker magnetic suspension densimeter due to the fluid-specific effect and its correction for use with gas mixtures containing oxygen
Daniel Lozano-MartÃn, MarÃa E. Mondéjar, José J. Segovia +1
Density measurements from single-sinker magnetic suspension densimeters need to be corrected to compensate for the magnetic effects of the measuring cell materials and the fluid on…
