| Abstract |
Fossil fuels have been depleted gradually and new energy resource which can solve this shortage is needed now. Methane hydrate, non-polluting new energy resource, satisfies this requirement and considered the precious resource prevent the global warming. Fortunately, there are abundant resources of methane hydrate distribute in the earth widely, so developing the techniques that can use these gases effectively is fully valuable. the work presented here is to develop the skill which can transport and store methane hydrate. As a first step, the equilibrium point experiment has been carried out by increasing temperatures in the cell at fixed pressures. The influence of gas consumption rates under variable degree of subcooling, stirring and water injection has been investigated formation to find out kinetic characteristics of the hydrate. The results of present investigation show that the enhancements of the hydrate formation in terms of the gas/water ratio are closely related to operational pressure, temperature, degrees of subcooling, stirring rate, and water injection. |
