natural gas; gas hydrates; transportation and storage of gas


In this paper, we consider the problem of transportation, accumulation and storage of natural gas in the case, when traditional technologies of pipeline transportation or in the form of liquefied or compressed gas are ineffective. Gas hydrates at low pressures and temperatures below 273 K can be stable during relatively long time. At that, the losses of gas are significantly slowed down by the effect of self-preservation or forced conservation by the ice crust. The study of some technological elements is important for this. At that, the important factor is the choice of the method of gas hydrates production.
This work suggests the technology for production of natural gas hydrates by the effect of high-amplitude pressure pulses on water saturated with the bubbles of methane. The advantages of this method over the other is intensification of the process of gas hydrates production due to a significant increase in the interface by crushing bubbles in the wave relative to the motion of gas bubbles in liquid and turbulizing the liquid motion behind the shock wave. This method skips the volumetric-diffusion stage of gas hydrate growth that allows an order gain in the rate of intensifying the process of hydrate formation in comparison with the similar processes.
