A model of gas hydrate formation on the surface of a slug of forming hydrate gas with inert gas admixture rising in a channel filled with liquid is suggested. Detailed analysis of the case of small concentrations of the inert admixtures in the gaseous phase is presented. Effect of heat released during gas hydrate formation on the rate of gas hydrate formation is investigated. Analytical formula for the rate of gas hydrate formation as a function of the concentration of the inert admixtures in the gaseous phase is derived. It is shown that an isothermal model of gas hydrate formation in the presence of inert gases underestimates a rate of gas hydrate formation in comparison with the nonisothermal model.
