Carbon dioxide (CO2) is widely recognized as the main cause of climate change affecting our planet. In recent years, the concentration of CO2 in the atmosphere has increased significantly due to the intensive combustion of fossil fuels. This study is devoted to the simulation of the 1D case of the CO2 capture process by aqueous Potassium carbonate...

This study deals with the simulation of membrane gas absorption of CO2 removal by methyldiethanolamine (MDEA) aqueous solution based nanofluid adsorbent, using hollow fibre membranes. The developed 1D model is based on mass balance equations for the shell, membrane, and tube sides of the contactor. Reversible chemical reactions between CO2 and MDEA...

Cement manufacturing is a highly energy intensive process, which resulting a large loss of energy at the level of the different plants, in other way the loss of energy in the form of heat is very significantly at the level of the cooler. This work focus on direct waste heat recovery, where tertiary air was recovered to the preheater, for this study...

Bisphenol A (BPA) is the principal component of many polymers such polycarbonate (PC) and epoxy resins. These polymers are commonly used to make baby bottle, drinking water bottle, CDs, food containers, dental sealant, and so on. BPA can migrate from PC to foods and beverages. In order to establish the relationship between the migrant contaminant a...

The simulation of solutes transport in porous media is of importance in many disciplines including CO2 sequestration simulations, the evaluation of underground water quality, nuclear waste simulations, and petroleum reservoir engineering. We present a numerical method for coupling 3D transport with equilibrium reactions. Our method is based on a fi...

The present study concerns the elimination of toxic metallic cations such as Copper, from waste waters by means of orange peels as an adsorbent. A priori, the solid support was thermally pre-treated and the copper II adsorption was carried out batchwise. The influence of various parameters such as the contacting time, the initial copper concentrati...

The quantitative prediction of solute transport presents a great interest in many fields where numerical modelling of solute transport through heterogeneous porous media may be regarded as an efficient tool. In the present study, numerical experiments of a 1D model were performed by means of a method based on the Finite Volume (FV) scheme using ope...

Liquid-liquid extraction columns are a quite good illustration of a two-phase flow system. They are used for contacting two immiscible liquid phases, flowing co or counter currently, and are simply vertical tubes having often, at their base, a distributor which can be a perforated plate or a series of nozzles, enabling the dispersion of one phase (...
