the purpose of this study is to investigate the role of oil, natural gas and coal consumption in iran’s economic growth during the periods from 1980 to 2012. the stationary analysis is performed by using adf and phillips-perron unit root test and auto-regressive distributed lag (ardl) approach was used to test for co-integration between the variables. the findings show that the variables are co...

In this study, the energy consumption in the food and beverage industries of Iran was investigated. The energy consumption in this sector was modeled using artificial neural network (ANN), response surface methodology (RSM) and genetic algorithm (GA). First, the input data to the model were calculated according to the statistical source, balance-sheets and the method proposed in this paper. It ...
Prediction of residential natural gas consumption in 20 next years was performed in this paper. Artificial neural network (ANN) was used to predict the natural gas in the Kerman, the biggest province in the Iran. The Kerman is included with ten important cities where gas consumption was estimated in each city. The minimum temperature in each year, population growth rate and number of each year ...

Natural gas plays a key role in Iran’s economy and using its shadow price in allocating it to different sectors can lead to optimal use of this resource. This study uses a non-linear input-output model to estimate the shadow price of natural gas in different economic sectors in Iran. The study uses values of the input-output table constructed by the Statistics Center of Iran for the year 2011. ...
hydrates are crystalline compounds similar to ice, with guest molecules like methane and ethane trapped inside cavities or cages formed by the hydrogen bounded framework of water molecules. these solid compounds give rise to problems in the natural gas oil industry because they can plug pipelines and process equipments. low dosage hydrate inhibitors are a recently developed hydrate control tech...
