摘要：
In this paper, an adsorption-energy model of the kinetics of the formation of hydrates in gaswater (liquid and ice) systems and their dissociation is proposed. It is based on the concepts about the process of adsorption of gas in the hydrate, its state in the crystal lattice, and energies released during the formation of the hydrate and absorbed during its dissociation. The metastable states of the gas hydrate (the effects of conservation and self-conservation) during its dissociation are taken into account in the model. It is possible to solve a complex of practical tasks within a wide range of thermobaric parameters and taking into account the factors affecting the kinetics of the formation and dissociation of hydrates using this model.
