in this study, mass transfer coefficients (mtc’s) of natural gas components during hydrate formation are reported. this work is based on the assumption that the transport of gas molecules from gas phase to aqueous phase is dominant among other resistances. several experiments were conducted on a mixture of natural gas at different pressures and temperatures and the consumed gas was monitored an...

in this paper, an adaptive-network-based fuzzy inference system (anfis) is used for forecasting of natural gas consumption. it is clear that natural gas consumption prediction for future, surly can help statesmen to decide more certain. there are many variables which effect on gas consumption but two variables that named gross domestic product (gdp) and population, are selected as two input var...

Recent increases in natural gas reserve estimates and advances in shale gas technology make natural gas a fuel with good prospects to serve a bridge to a low-carbon world. Russia is an important energy supplier as it holds the world largest natural gas reserves and it is the world’s largest exporter of natural gas. Energy was one of the driving forces of Russia’s recent economic recovery from t...

Global gas markets feature two types of suppliers: piped gas and LNG exporters. Pipelines have a high degree of “asset specificity”: once built, they are physically bound to a particular route. LNG is transported by tanker, with a choice of export markets. Put simply: LNG is mobile, pipelines are not. This paper uses game-theoretic modelling to show how its commitment to serving a single market...

This study examined the factors that influence agricultural production and exports with specific reference to the natural rubber in India. Secondary data was used for this study. Ordinary Least Squares (OLS) technique was used in analyzing the relevant data. The OLS findings revealed that natural rubber production is significantly (p<0.05) by export of natural rubber (β=0.05), stock (β=0.21) an...

the natural gas consumption in iran has been continuously increasing due to several reasons including low prices of natural gas, development of gas supply networks, people’s salary increase, incorrect consumption culture and the increase of national economy growth.  although, the global natural gas consumption has increased by 38% since 2001, the national consumption in iran has increased by 11...

the hcci combustion process is initiated due to auto-ignition of fuel/air mixture which is dominated by chemical kinetics and therefore fuel composition has a significant effect on engine operation and a detailed reaction mechanism is essential to analysis hcci combustion. a single zone-model permits to have a detailed chemical kinetics modeling for practical fuels. in this study a single-zone ...

natural gas is often associated with nitrogen and heavy compounds. the heavy components in the natural gas not only can feed downstream units, owing to the low temperature process may be formed solid as well. therefore, heavy components separation can be a necessity and produce useful products. virtually, all natural gases are containing nitrogen ​​that would lower the heating value of natural ...

kharg island as the most important oil export terminal of iran has faced entrance of various oilmaterials, so it seems necessary to know about the amount of these marine oil pollutants and their origin in this area. oil hydrocarbons has entered in this water body as a result of numerous human activities like extraction, refinement, transmission and export of raw oil or from natural and biologic...
