Item APPROCHE EXPERIMENTALE DE LA LONGUEUR DU ROULEAU DU SURFACE DU RESSAUT HYDRAULIQUE DANS UN CANAL PROFILE EN “U” A FOND RUGUEUX(جامعة الوادي - university of el oued, 2013) Ghomri, A; Riguet, F; Debabeche, MThis study aims to experimentally evaluate an experimental approach to the length of the roller surface of the hydraulic jump controlled by threshold, moving in a channel profile 'U' rough bottom roughness for different tested. a functional relationship in dimensionless term, linking the different characteristics of the projection, showing the effect of the roughness of the channel bottom was obtained.Item ASPEN HYSYS SIMULATION AND COMPARISON BETWEEN ORGANIC SOLVENTS (SULFOLANE AND DMSO) USED FOR BENZENE EXTRACTION(جامعة الوادي - university of el oued, 2013) Zaiz, T; Lanez, H; Kechida, BDue to the high increase of the production of aromatic hydrocarbons: benzene, toluene and xylenes BTX from oil because of the large activity of their big markets especially with the availability of great quantities of these aromatic fractions in the oil. This study has two main parts the first presents a general vision of the aromatic hydrocarbons, the second is going to focus on the liquidliquid extraction with the selected solvents as a separation method. The solvent selection depends on many properties. In this second part there will be a simulation (conception and execution) of the liquid-liquid extraction of aromatics by two different organic solvents Sulfolane and DMSO followed by a comparison between the results obtained by the simulation. The simulator used will be ASPEN HYSYS 7.2. The results of the simulation showed that the use DMSO is better than Sulfolane because of the separation efficiency the economic value and the regeneration rate although its use is more dangerous (more toxic) than the SulfolaneItem AN OVERVIEW OF THE POLYMER GEL TECHNIQUE TO IMPROVE THE EFFICIENCY OF WATER FLOODING INTO OIL RESERVOIRS (WITH INTRODUCTION OF A NEW POLYMER)(جامعة الوادي - university of el oued, 2013) Arjmand, O; Ahmadi, M; Hosseini, LAn important property of polymer gels is that the injected fluid in the fracture area with high permeability moves and can form a solid mass, in result of water and gas permeability because of the formation of this layer will be decreased. In gel polymer techniques first amount of the polymer solution is injected into the reservoir with a low rate, then the cross link solution such as aluminum or magnesium citrate is injected into the reservoir and gel to be figured. Therefore, improves oil recovery and reduces the percent of water production. This study concerns a light review on gel polymer process and this study introduces a new polymer with superior flooding property to water shut - off, too
