Abstract: In this paper the process of surfacing of hydrate particles in a liquid is viewed. Typical depths at which hydrate formation is accompanied by bubbling or unchanged hydrate particles and small depths, which are accompanied by decomposition of hydrate ascent particles are singled out. It is assumed that the intensity of hydrate formation and decomposition is determined by the convective heat exchange with the ambient particle of water.

Keywords: change of fase, gas hydrate, surfacing of hydrate particles.
