This work attempts to address the quest of removing carbon dioxide from flue gas streams help preserve environment. It is based on a model that able describe solid-liquid-vapour and solid-vapour phase equilibria for ternary system N2-O2-CO2 at pressures 5 130 bar over wide range temperature (140 220 K). Furthermore, corresponding state-of-the art solid-vapor (SV) CO2 capture/separation unit dev...

We review the current state of knowledge of phase separation and phase equilibria in porous materials. Our emphasis is on fundamental studies of simple fluids (composed of small, neutral molecules) and well-characterized materials. While theoretical and molecular simulation studies are stressed, we also survey experimental investigations that are fundamental in nature. Following a brief survey ...

A new apparatus based on a static-analytic method was developed in this work to perform high-pressure vapor-liquid equilibria measurements up to 68 MPa and 373 K. In order to validate this new apparatus, vapor-liquid equilibria of the binary system CO2 + ethanol was measured at temperatures of 313, 323 and 338 K and pressures from 1.2 to 11 MPa. Results were compared with data from the literatu...

A comprehensive mixed-solvent electrolyte model has been extended to calculate liquid– liquid equilibria in water–organic salt systems. Also, it has been applied to calculate phase equilibria and speciation in strongly associating systems such as sulfuric acid/oleum (H2SO4+SO3+H2O) in the entire concentration range. The model combines an excess Gibbs energy model with detailed speciation calcul...

The determination region of solubility of methanol with gasoline of high aromatic content was investigated experimentally at temperature of 288.2 K. A type 1 liquid-liquid phase diagram was obtained for this ternary system. These results were correlated simultaneously by the UNIQUAC model. The values of the interaction parameters between each pair of components in the system were obtained f...

An extension of the transferable potentials for phase equilibria-united atom (TraPPE-UA) force field to acrylate and methacrylate monomers is presented. New parameters were fit to the liquid density, normal boiling point, saturated vapor pressure, and (where experimentally available) critical constants of 1,3-butadiene, isoprene, methyl acrylate, and methyl methacrylate using Gibbs ensemble Mon...

The adsorption thermodynamics of copolymers, based on ethylene oxide (EO) and propylene oxide (PO) units, at the laponite (RD) clay/liquid interface was determined at 298 K. The copolymer nature was tuned at molecular level by changing the hydrophilicity, the architecture and the molecular weight (Mw) keeping constant the EO/PO ratio. Polyethylene (PEGs) and polypropylene (PPGs) glycols with va...
