Aqueous polymers used for enhanced oil recovery (EOR) application is considered a complex fluid. It can exhibit Newtonian and Non-Newtonian behavior depending on the velocity or the stresses that it is submitted during the flooding process. Therefore, the polymer flooding project ...

For membrane gas separation modeling, some assumptions are made. One of the most typical approaches in such modeling is to assume a plug flow in the feed/retentate channel and ideal mixing conditions in the permeate channel. For membranes with high permeation, the permeate flux could be ... En savoir plus

During the last three decades, lithium-ion batteries have become the choice of power source for most portable electronic devices. During a discharge process, intercalated lithium, which is initially stored in the anode, de-intercalates, diffuses out in the electrolyte, reaches the ... En savoir plus

The material wood is frequently used in construction industry for several elements such as window frames. However, as a hygrothermal material, wood is sensitive to moisture induced damage. In this context, the moisture uptake of wood based windows logged with an integrated relative ... En savoir plus

Oxygen transfer through ceramic membranes at high-temperature can substantially reduce costs respect to conventional separation methods. With the aim to improve the determination of the properties of the ceramic materials, a lab-scale permeation set-up was modeled using the Chemical ... En savoir plus

One of the challenges associated with the wire-arc additive manufacture (WAAM) of metals is to provide adequate inert gas shielding, not only for the molten pool, but also for the long reactive metal surface that follows it. For Ti-6Al-4V, it has been shown that increased levels of ... En savoir plus

One of the most critical aspects on water electrolysis is gas-liquid separation, especially in systems with forced convection. The main problem of this kind of circulation is that a gas fraction could return to the electrolysis circuit. A suitable design of separator devices could be a ... En savoir plus

The global demand for sulfuric acid has been forecast to grow at an average of 2.6% per year from 2005 – 2010. The primary objective of this work is to analyze the performance of various heterogeneous catalyst shapes that have been proposed for the oxidation of SO2 to SO3 used in the ... En savoir plus

Magnetophoresis of non-magnetic particles is the induced motion of non-magnetic particles suspended in magnetic media on the application of a magnetic field gradient. Magnetophoresis can be used in special separation devices to separate colloidal particles based on their sizes. ... En savoir plus

Oxygen-free methane aromatization has been attracting growing attention due to a potential means for producing high valuable products such as aromatics and hydrogen. Many studies have been focused on catalysts screening and characterization, and elementary thermodynamic steps of the ... En savoir plus
