The production of methanol is performed through the reaction of carbon monoxide and
hydrogen these two component constitute the synthesis gas this latter is obtained by the
reaction between the natural gas and water ...
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 ...
The objective of this study is to develop a complete mathematical model for simulation and optimization of catalytic reforming process. The model is developed from a base of fundamentalchemistry.
Catalytic reforming is ...
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 ...
The microwaves present a very significant application in physics, it is the characterization of materials. In our project, we are interested in uniaxial materials (determination of their tensor of permittivity). The test ...
The mainly purpose of this manuscript is to develop computational code to estimate solar irradiance for photovoltaic and thermal systems in Algeria. Computational code developed allows a numerical and graphical visualization ...
A simple technique (solvent phase inversion) has been used to prepare biodegradable
polymeric membranes based on a mixture of clay (chemical treated, no treated) and starch.
The disc samples of 100-300μm thickness were ...
The objective of this work is to establish a program that determines the electron
trajectories and backscattered electrons in a solid material bombed by an electron beam and
using the statistical Monte Carlo method. From ...
The polymers are less expensive and much usually in treatment of water. And from of these polymers: the cellulose which takes important place and his chemical structure.
This polysaccharide is linear withdraw in his surface ...
The work presented in the context of this thesis concerns the determination of the distribution of electron density of compound chemical formula C8H9NOS from a spectrum of high-resolution X-ray diffraction on single crystal ...
The aim of this work is study the degradation of a xanthene dye called "Erythrosine" (Er) in homogeneous and heterogeneous environments.
In a homogeneous medium, discoloration and degradation of Er was carried out by ...
Textile dyes are classified as refractory organic compounds and non-biodegradable.
They represent a potential danger to humans and the environment.
The need for new technologies, effective and energy efficient to reduce ...
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 ...
Provide products of sulphur and nitrogen for the following treatment units.The majority of the units upstream use catalysts sensitive to nitrogen but especially to sulphur.The environmental standards on the quantities of ...
