Abstract

A new method of gas-hydrate formation based on underwater boiling of condensed gas as a result of depressurization is experimentally investigated. Advantage of this method over others is intensification of the gas-hydrate formation process as a result of growing interphase surface due to boiling. Active boiling leads to collisions and deformation of bubbles with the hydrate film formed on the interphase surface. As a result, the hydrate film detaches, which makes it possible to avoid the volume-diffusion gas-hydrate growth stage, and the hydrate formation rate does not decrease. Heat released during hydrate formation is compensated for by heat absorption during boiling. Due to overlapping of these processes, there occurs rapid growth of gas-hydrate mass, which yields a gain in the process intensification rate by an order of magnitude over all the known analogs.
