In the medium term, gas hydrate reservoirs in the subsea sediment are intended as deposits for carbon dioxide (CO2) from fossil fuel consumption. This idea is supported by the fact, that CO2 hydrates are more stable than methane hydrates at certain conditions. The potential of producing ... En savoir plus
The Life+ GreenWoolF project is aimed at demonstrating that green hydrolysis with superheated water is an effective way to convert wool wastes into organic nitrogen fertilizers. The core of the process is represented by the reaction tank (Figure 1) in which the hydrolyses reaction takes ... En savoir plus
Capacitive deionization (CDI) is a desalination technology which is based on the storage of ions in the electrical double layer of a pair of oppositely polarized porous carbon electrodes, which are usually assembled using activated carbon particles (Figure 1). It is efficiently deployed ... En savoir plus
The annular reactor is a very useful design to carry many chemical reactions. In this study, COMSOL Multiphysics® software was used to study the isothermal mass transfer from the inner side of the outer tube of the annular reactor in the range of 200 En savoir plus
Horizontal-Flow Constructed Wetlands (HFCWs) are a particular type of biofilter, and as such they rely mostly on the activity of bacterial communities to treat wastewater. Bacterial growth in HFCWs induces dramatic changes in its hydraulic and hydrodynamic behaviour (bioclogging), which ... En savoir plus
Packed beds are important in the chemical industries. Computational fluid dynamics (CFD) can simulate detailed flow and scalar transport in packed beds for improved understanding and quantitative information. We present simulations of single-phase gas flow, conjugate heat transfer and ... En savoir plus
The conventional route to hydrogen production is by steam reforming of methane (MSR) in a multitubular packed bed. With the increasing use of biodiesel as a renewable fuel, interest has grown in steam reforming of the excess glycerol produced as a side product (GSR). We use COMSOL ... En savoir plus
Hydrocooling is the process by which warm produce is chilled with water. The chilling of warm produce generates a negative pressure differential between the produce (warm) and (cold) water due to the condensation of water vapor inside the produce which forms a vacuum and can pull in ...

This work used the 3D CFD modeling to investigate non-uniform deactivation in packed bed reactors of low aspect ratios under steady state and dynamic operations. In order to explore the effects of condition of instability on local deactivation, detailed knowledge of flow dynamics (i.e. ... En savoir plus
The process of accelerated curing of pre-cast concrete has a significant importance in the thermal behavior of concrete. A multiphysics model that describes hydration and heat and mass transport in cement based materials was developed. The hydration reactions are described by a maturity ... En savoir plus
