Gas hydrates are crystalline compounds formed by inclusion of small gas molecules into a lattice constructed by water. Development of a mathematical model for qualitive quantitative description
of hydrate crystal growth rate is the basic aim of this work. The difference between the temperature of crystal surface and that of the liquid bulk is employed as driving force of crystal growth. Paran1eters of model for hydrate formation from methane and ethane are calculated and it was shown that the heat transfer model combined with distribution of growing particles is capable of describing the experimental data.
