Many industries, such as plastics, and textile use dyes to color their products and also
consome substantial volumes of water .Due to their good solubility, synthetic dyes are common water pollutants and they ...
Methanol is synthesized starting from the synthesis gas (CO + H2 +CO2), this last is obtained starting from methane CH4 and from the water vapor. Rough methanol product contains some undesirable compounds; this is why the ...
The present work is devoted to the study by diffraction of x-rays of the structure détermination in the organic compound with nonlinear optical properties, 5-(p-nitrobenzylidène)-2-thioxo-3-N(o.OEthylphénylthiazoline-4-one ...
A determining of some properties of zeolites 3A, 5A, 10X, Y and 4A DG-TRISIV and the moisture content in natural gas of GL2/Z have been studied. After describing the dehydration process, the different zeolites were chosen ...
Ceramic support was prepared from kaolin. The characterization of the porous properties and structure of the support synthesis was carried out by Scanning Electron Microscopy (SEM), absorption rate, shrinkage rate and ...
Since the advent of the computer tools, and the increasing performance of the apparatuses of diffraction of x-rays, the determination of the crystalline structure of the monocrystals, starting from the data of x-rays, ...
In recent years, the regulation of water quality has become increasingly strict. This is due to a growing social concern on the preservation of the environment. For this purpose, the environmental research has undergone ...
The primary goal of our works is the calculation method of simulating a gas separation (rectification).
tray by tray method allows us to control all parameters affecting influencing the process such as temperature, pressure ...
A part of the Algerian natural gas is destinated to the exportation, where it should be liquefied is a necessity; this last operation is possible except if we eliminate the CO2 which the natural gas contains.
The reduction ...
Our study is based on the synthesis and the application of the membrane prepared from treated /non treated clay and starch at different volumes and concentrations. The best membranes found has been tested for their abilities ...
