in this paper, first design and analysis history of full metal cng cylinders for vehicle are investigated. next with respect to the cng worldwide standards, a full metal type cylinder is designed and analysed. then the numerical analysis results and practical results are compared, and the correctness of the investigation is verified. in the end, the most suitable alloy with respect to the dimen...
during natural gas processing, water in natural gas may cause to hydrates formation in pipelines which may lead to serious damages to process equipments. given the problems raised by present of water in natural gas, glycol solvent uses to remove water.in contact of glycol with gas always an amount of btex and voc absorb along with water, which on glycol recovery process, these substances separa...
The accurate modeling of the fast-fill dynamics occurring in Compressed Natural Gas (CNG) fueled vehicle storage cylinders is a complex process and to date those dynamics have not been thoroughly studied. Here, based on first law of thermodynamics, conversation of mass and thermodynamics properties table a numerical method has been developed to study fast filling process of natural gas vehicle’...
the preparation of air–fuel mixture is considerably dependent on fluid flow dynamics to achieve improved performance, efficiency, and engine combustion in the appearance of flow. in this study, the effects of mixtures of hydrogen and compressed natural gas (cng) on a spark ignition engine are numerically considered. this article presents the results of a direct-injection engine using methane–hy...
Nowadays, increased attention has been focused on internal combustion engine fuels. Regarding environmental effects of internal combustion engines particularly as sources of pollution and depletion of fossil fuels, compressed natural gas has been introduced as an alternative to gasoline and diesel fuels in many applications. A high research octane number which allows combustion at higher co...
Biogas derived from organic wastes is considered as good alternative to petroleum fuels. It can be used in compression ignition (CI) engines, because of its better mixing ability with air and clean burning nature. Biogas is produced by anaerobic digestion of various organic substances such as kitchen wastes, agricultural wastes, municipal solid wastes, cow dung etc., in absence of oxygen, which...
We report hydrogen storage at an ordinary pressure due to a bottle-neck effect of an ultramicroporous crystal. Stored hydrogen was kept at an ordinary pressure below -110 °C. The amounts of stored hydrogen gas linearly correlated with the initial pressures. These phenomena suggested the ultramicroporous tunnels worked as a molecular gas cylinder.
The risks of ferromagnetic compressed gas cylinders becoming projectiles in an MR environment are well known (12). The recent death of a child from such an incident reinforces the potential for disaster (3).
