Natural gas storage process in aquifer, due to fluid flow behavior of gas and water in the porous medium and because of their contact with each other under reservoir conditions, faces several challenges. Therefore, there should be a clear understanding of the injected gas behavior before and after the injection into the reservoir. This research simulates the natural gas storage in aquifer by us...
T he environmental issues have received a lot of attention in recent years. Since environmental pollution is one of the issues that may damage the ability of future generations, it is important to examine the determinants of the environment quality. The main objective of this study is to investigate the impact of urban and rural income inequality on natural gas consumption in Iran. To this...
Recently natural gas global market attracted much attention since it is cleaner than oil and also is cheaper than renewable energy sources. However, price fluctuations, environmental concerns, technological development, unconventional resources, energy security challenges, and shipment are some of the forces made energy market more dynamic and complex in the last decade. Studying of natural gas...
in this work the likelihood of asphaltene deposition problems during dynamic displacement of oil by natural gas in unconsolidated porous media is experimentally inspected. the two different rock materials, limestone and sandstone, are used as a representative of porous media. dynamic flow experiments indicate that the increase of natural gas injection increases asphaltene deposition in the unco...
Natural gas is now the largest source of energy in the international community and Iran has the largest natural gas reservoirs in the world. The development of gas networks has covered 98% of the urban population and more than 85% of the rural population of Iran. On the other hand, the exporting and conversion of natural gas into petrochemical products, electricity generation and use for indust...
Iran’s environmental condition is critical, since it is experiencing desertification, unsustainable development and overpopulation. The objective of this study is power source replacement in natural gas stations that operate with natural gas compressors, through using electrical motors, which can be fed by a 160 MW geothermal power plant, as an alternative to gas turbines. Application of such a...
Today there is consensus regarding the importance of predicting the price of energy carriers for economic development, including natural gas as a preferred energy source on environmental grounds. In this paper we analyze the nonlinear behavior of natural gas prices over time by use of the Grey Method (GM), Developed Grey Method (DGM), Fractal Discrete Grey Method (FDGM) and a compound Method II...
The aim of this study is to evaluate a heavy duty diesel engine operation under reactivity controlled compression ignition combustion fueled with diesel oil and natural gas enriched with hydrogen and nitrogen addition. In this study, a single cylinder heavy– duty diesel engine is set to operate at 9.4bar gross IMEP (Mid- Load). The amount of injected diesel oil per cycle into the engine combust...
