The CO2 removal from N2 using unconventional techniques based on different (various) membranes has known a significant interest in industry. Mixed matrix membranes combine the advantages of organic (easily processable and low cost) and inorganic phases (high selectivity, mechanical resistance, chemical and thermal stability). In this study, membranes with polysulfone matrix and MCM-41 (silica) as filler were obtained, characterized and tested. The mixed matrix membranes were prepared by casting method. The effects...

The interpretation of well tests is a tool for the detection of well and reservoir problems, which based on the determination of several parameters such as permeability, skin, average reservoir pressure, flow capacity (kh ), effective length, boundary reservoir, and type of wellbore storage, etc. The knowledge of these parameters will allow us to make the production forecast and the resolution of production problems. For this, We have chosen six production wells located in the Haoud Berkaoui oil field, the interpr...

Disposal of increasing waste production in mining is currently a serious problem of civilization. The most common way to dispose of mining waste is storing them on impoundments. The hydraulic transport is advantageous from the standpoint of service and perhaps economy too, but the geotechnical properties of the resulting sediment are poor especially when saturated. For the design and construction of safe dumps with minimum impact on the environment the knowledge of the geotechnical properties of sedimented mining ...

The present research aims at determining the influence of physical and mechanical properties of the soil (resistance to penetration) and of the liquid pollutant in case of soil cleaning and self-cleaning processes. Different forces operate on the water in the soil, and they permanently modify themselves depending on the quantity of water in the soil and its properties (texture, porosity, density). The leaching speed of liquid pollutant in the soil is a variable measure, for one and the same type of soil, and it de...
