Abstract: The problem of acoustic effect on the liquid with hydrate-generating gas bubbles is solved. The gas used were Freon-12 and Methane. The system was in the equilibrium hydrate-generating conditions. The dispersion equation for the wave number is obtained. The dependences of the phase velocity and the decrement of dumping on the dispersity of the gas-liquid mixture and on the frequency of disturbance under the hydrate-generating conditions and in the absence of hydrate-generating, were obtained. The parameters affecting the intensity of the gas transition into the hydrate state were defined.

Keywords: bubbly liquid, the acoustic wave, equilibrium state, hydrate-generative.
