Streszczenie: M.A. Pavlenko, B.A. Kutnuy, N.M. Abdullah. Gas hydrates forming and decomposition
conditions analysis. The concept of gas hydrates has been defined; their brief description
has been given; factors that affect the formation and decomposition of the hydrates have
been reported; their distribution, structure and thermodynamic conditions determining the
gas hydrates formation disposition in gas pipelines have been considered. Advantages and
disadvantages of the known methods for removing gas hydrate plugs in the pipeline have
been analyzed, the necessity of their further studies has been proved. In addition to the
negative impact on the process of gas extraction, the hydrates properties make it possible to
outline the following possible fields of their industrial use: obtaining ultrahigh pressures in
confined spaces at the hydrate decomposition; separating hydrocarbon mixtures by successive
transfer of individual components through the hydrate given the mode; obtaining cold
due to heat absorption at the hydrate decomposition; elimination of the open gas fountain
by means of hydrate plugs in the bore hole of the gushing gasser; seawater desalination,
based on the hydrate ability to only bind water molecules into the solid state; wastewater
purification; gas storage in the hydrate state; dispersion of high temperature fog and
clouds by means of hydrates; water-hydrates emulsion injection into the productive strata
to raise the oil recovery factor; obtaining cold in the gas processing to cool the gas, etc
