Crude oil blending is an important unit operation in petroleum refining industry. A good model for the blending system is beneficial for supervision operation, prediction of the export petroleum quality and realizing model-based optimal control. Since the blending cannot follow the ideal mixing rule in practice, we propose a static neural network to approximate the blending properties. By the d...

in recent decades energy sector has been most important division in sociopolitical national and international dialogs. policy making in energy sector in iran is a strategic subject because of independency of our national revenue to oil & gas export in one way and huge oil & gas reservoirs in iran (137 billion barrel in oil and 28.3 million cubic meter in gas) in other hand. this paper investiga...

this study employs a gmdh neural network model, which has high capability in recognition of complicated non-linear trends especially with small samples, for modeling and predicting iranian gdp growth. first a fundamental model containing 7 independent variables together with dependent variable is designed and then by using deductive process and omission of one variable at a time, a total of 18 ...

Abstract:Gas export is one of the considerable choices in gas consumption to obtain foreign ex-change direct income by the government. Gas can be transformed and exported by various forms such as LNG and GTL. All forms of gar transformation and its export row gas with a convertible coefficient. Therefore, gas export means the total gas export through pipelines, LNG on the other forms of g...

this article analyses the effects of foreign exchange commitment and exchange rate unification policies on iran’s non-oil exports during the last three decades. in addition, the effects of these policies on non-oil exports have empirically been estimated. for this purpose, an export supply model was estimated using the econometrics technique of auto regressive distributed lag (ardl) and reliabl...

Energy has been the main pillar of the global growth and development. Amongst various sources of energy, oil has the largest share in the global energy consumption. As these energy reserves tend to decline, few regions, most notably the Middle East which has been at the forefront with the largest reserves, can fulfill the rising global energy demand. Even then, in view of its vast energy potent...

Increase in the exchange rate may not always promote export of non-oil production and exports of various goods; rather they might have different reactions to the exchange rate. Hence, in this study we tried to examine the effect of real effective exchange rate on Iranian pistachio export. The required data were collected from statistical yearbook of Iran's foreign trade, statistical yearbook of...
