“…Solubility measurements of solids in carbon dioxide were performed in an apparatus based on the static-analytic technique. This is mainly constituted by a high-pressure view-cell, a six-port two-way valve (Valco, C-2006E), a high-performance liquid chromatograph (Agilent, 1100 series), a syringe pump (Isco, 100DM), and an air bath (France Etuves, model XL074SP). The schematic diagram of the apparatus is presented in Figure .…”

The aim of this work is to present a new experimental apparatus based on the static-analytic method suitable to perform solubility measurements of solids in sub- and supercritical carbon dioxide. Mole fractions of dissolved solids are determined online via high-performance liquid chromatography. The studied binary mixtures are capsaicin in carbon dioxide from 298 to 328 K, hexadecanoic acid in carbon dioxide at 313 and 318 K, β-carotene in carbon dioxide at 298 and 313 K, and acetaminophen in carbon dioxide at 313 K. The experimental apparatus is also tested by circulating the fluid phase to measure the solubility of capsaicin in carbon dioxide at 298 K. Experimental solid solubilities in carbon dioxide are found to be in agreement with the solubility data reported in the literature. The Méndez-Santiago and Teja and the modified Chrastil models are used to correlate the experimental data.

“…Initially, the apparatus used was based on the static-analytic method and has been designed to perform fast determinations of vapor–liquid equilibria and critical pressures up to 60 MPa and 523 K . However, in order to determine other thermophysical properties within the phase equilibrium, a second experimental apparatus was developed to simultaneously determine at high pressures liquid–vapor equilibrium or vapor–liquid–liquid equilibrium and saturation densities. , Actually, both apparatuses are part of the experimental facilities of the Thermodynamics Laboratory.…”

In 1997, a new thermodynamic laboratory was create from scratch. Throughout 20 years of work, this laboratory has performed and reported experimental determinations of thermophysical properties, such as phase equilibria (VLE, SLE, SLVE), critical points of pure fluids and mixtures, volumetric properties (PvT), dynamic viscosities, supercritical fluid extraction (SFE), and studies on the formation of gas hydrates. Over time, experimental systems have been designed, developed, and/or modified according to the experiments. Besides, molecular simulations have been carried out, resulting in the proposal of equations of state based on perturbation theory. All of the measurements that have been carried out have reported the experimental uncertainty according to the NIST technical note 1297. In this work, experimental determinations of each thermophysical property, VLE, solid solubility in supercritical fluids, PvT, dynamic viscosities, and gas hydrate dissociation data, are reported in the 293.15–353.15 K temperature range and at pressures up to 30 MPa. The experimental uncertainty of reported data was determined and is mentioned for each property.
