Abstract

Clathrate hydrates are not only a huge source of energy, but also potentially interesting from a technological point of view due to their ability to bind water. According to generally accepted modern concepts, hydrates formed by individual hydrate-formers or their mixtures are non-stoichiometric inclusion compounds of a cellular type with the crystal lattice built of water molecules held by hydrogen bonds. The molecules of the hydrateformer are located in the internal cavities of the crystal lattice and are held in them by van der Waals forces. The article presents a formalized description of the hydrate formation process. A model of hydrate formation in gas-water systems is proposed. The model describes the processes occurring during hydrate formation in structures. It contains equations for calculating the main energy and molecular parameters of the hydrateformer, as well as the kinetics of the process.
