MODEL OF GAS HYDRATE FORMATION ON THE SURFACE OF A SLUG OF A PURE GAS

摘要

A model of gas hydrate formation at a surface of a slug of a pure hydrate forming gas is suggested. Gas hydrate formation at a low degree of subcooling and at pressure that does not considerably exceed the equilibrium pressure are investigated. The investigation analyzes cases of gas hydrate formation at the surface of a gas slug fixed in a channel by a descending fluid flow and gas hydrate formation at the surface of a gas slug rising in a channel filled with liquid. An expression for the time dependence of a slug's length is derived. [References: 10]
