Abstracts:

This work is aimed at consideration of the problem of gas and gas mixture accumulation, transportation and storage, when the conventional technologies of transportation in the pipeline or compressed and liquefied forms are often inefficient. It is known that gas hydrates at low pressures and temperatures below 273 К can be stable during relatively long periods of time. Moreover, their dissociation can be significantly decelerated by the effect of self-preservation or forced conservation by the ice crust. This requires investigation and adjustment of technology. For this purpose the choice of the method for gas hydrate production is important. The technology of methane hydrate production through the effect of high-amplitude pressure pulses (shock waves) on methane-saturated water with methane bubbles is suggested in this work. The advantage of this method in comparison with the known analogues is significant intensification of the process of gas hydrate formation. This occurs due to a considerable increase in the interface, bubble fragmentation in the wave, relative motion of gas bubbles in liquid, and turbulization of liquid motion behind the wave. This allows us to skip the volumetric-diffusion stage of gas hydrate growth; in turn this provides a gain in the rate of hydrate formation intensification by an order and more in comparison with other methods.
