[Open source software] Equations of State

We present a set of MATLAB programs for the calculation of phase equilibrium and other thermodynamic properties using different equations of state (classical cubic equations, cubic equations with excess Gibbs energy mixing rules, group contribution equations and SAFT equations). All  programs are open-source and have been designed to be easily reusable using an object-oriented programming […]

Optimisation of the direct synthesis of H2O2 in water

Hydrogen peroxide (H2O2) is a green chemical compound widely used because of its strong oxidant properties (Green Chemistry). Some of the hydrogen peroxide applications are related with bleaching process in paper and textile industries, chemical synthesis and waste water treatment. High Pressure Process Group in collaboration with Åbo Akademi from Turku (Finland) have deeply studied […]

Hydrogen storage in microparticles of silica aerogel for mobile applications

The application of fuel cells using hydrogen as their energy source in vehicles or electronic equipment requires the development of new hydrogen storage devices. Current needs: The simplest and most obvious storage solutions such as compressed gas bottles or cryogenic tanks have important disadvantages due to the low gravimetric/volumetric density of the former (40g/L at […]

CFD Modelling – Development of computational tools for modeling the behavior of supercritical water oxidation reactions working under hydrothermal flame regime

      Supercritical water oxidation (SCWO) is an useful technology for the destruction of waste. In presence of hydrothermal flames (yes, a flame in aqueous media!) complete oxidation of organics is achieved in less than 1 s. The properties of water above its critical point (374◦4 C, 22.1 MPa) make possible the destruction of […]

Development of hydrogen storage materials by impregnation of hydride precursors in functionalized aerogel supports

     Aerogels are a class of materials with extraordinary properties like high porosity, low density, high thermal insulation value, ultra-low dieletric constant or low index of diffraction. That makes them suitable materials for different interesting applications: thermal insulation, drug encapsulation, desiccant, acoustic barrier, heat storage, supercapacitor, hydrogen storage, catalytic support, adsorption of toxic compounds […]

[Thesis] Enhanced extraction of natural substances using microwave energy

Process intensification is proposed using microwave and ultrasound energy in order to improve organic material liberation from natural cells (wastewater sludge, microalgae and grape marc). Enhanced process kinetics are achieved after a short pre-treatment stage up to the boiling temperature, followed by the conventional procedure. The novel technologies are compared to conventional thermal treatment in […]

SHYMAN Project reaches the midpoint. Hydrothermal synthesis of nanoparticles is for real -news-

Nanoparticles are changing the way we conceive materials, boosting novel applications by tailored design of properties. ShyMan Project (ca. 6 million euro) is developing hydrothermal technology in supercritical water by a combination of the expertise of universities (Nottingham, Valladolid, etc) and companies (Solvay, REPSOL, PPG, etc.). Valladolid university is the second biggest partner with a […]
