Iran is ranked as the ninth largest greenhouse gas producer in the world, with an annual emission of nearly 180 million tons of CO2 by thermal power plants.. The purpose of this research is to simulate and optimize the optimal economic and environmental load dispatch and a portfolio of efficiency improvement strategies on both supply and demand sides in MT1, MT2, and EEP scenarios in using the ...

This paper introduces the source and utility circumstance of natural gas in China. The utility circumstance of natural gas is discussed in detail, such as, natural gas as feedstock is produced to acetylene; natural gas is used to cut metal; natural gas is applied to generate ethylene; natural gas instead of heavy oil is fired to produce chromium trioxide. In so doing, the energy demand of China...

We examine the main political, market and regulatoryissues concerning natural gas use in the Mexican powergeneration sector. We also study the impacts of a technologydiversification policy regarding the primary energy used togenerate electricity. For that, we make use of the LEAPsystem (Long-range Energy Alternatives Planning-SEI Bos-ton) in order to simulate two scenari...

Global food demand is increasing rapidly, as are the environmental impacts of agricultural expansion. Here, we project global demand for crop production in 2050 and evaluate the environmental impacts of alternative ways that this demand might be met. We find that per capita demand for crops, when measured as caloric or protein content of all crops combined, has been a similarly increasing funct...

اکثر خطوط لوله انتقال gas-condensate در مناطق نفت خیز ایران، دارای قطر زیاد و تحت فشار بالا، درخارج از محدوده شرایط به کار رفته درایجاد مدل های دوفازی موجود می باشند. مدلهای فعلی، عموما براساس اطلاعات تجربی بدست آمده از لوله های کم قطر، در فشارهای پایین و تحت شرایط آزمایشی با مقدار مایع بیش از 10 ارائه گردیده اند. و به دلیل آنکه میزان مایع جمع شده در خطوط انتقال گاز و یا gas-condensate کمتر ازا...

With the rapid depletion of conventional natural gas resources in China and the increasing demand for natural gas as well as the improvement in the exploitation technologies of natural gas, the development of unconventional natural gas resources is rather urgent and feasible day by day and possible at the same time. However, the development of unconventional natural gas fields in China started ...

The ability of Artificial Neural Network (ANN) for estimating the natural gas demand load for the next day and month of the populated cities has shown to be a real  concern. As the most applicable network, the ANN with multi-layer back propagation perceptrons is used to approximate functions. Throughout the current work, the daily effective temperature is determined, and then the weather data w...

Emissions of more than three-quarters of greenhouse gases by the energy sector have affected climate change in various economic, political and social sectors. Climate change is affecting energy consumption, including natural gas. This article deals with the future of natural gas consumption in the country with regard to climate change until 2030 using a combined approach of econometrics and sce...

In this paper, we use the Global Gas Model to analyze the perspectives and infrastructure needs of the European natural gas market until 2050. Three pathways of natural gas consumption in a future low-carbon energy system in Europe are envisaged: i) a decreasing natural gas consumption, along the results of the PRIMES model for the EMF decarbonization scenarios; ii) a moderate increase of natur...
