Resumen

© 2019 American Chemical Society. 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.
