About some issues on kinetics of gas hydrates generation
R. A. PanahovThe article describes situation of gas hydrates generation and indicates key factors explaining generation mechanism of crystal structures of gas hydrates in gas-water system under certain thermodynamic conditions. Monomolecular layer of water surface is indicated to be in unbalance condition. Different characteristics of monomolecular upper surface of water in relation to water within the volume are indicated. Conclusions of experiment works carried out by a number of researchers on hydrate generation and water self-absorption field were indicated and analyses have been carried out. Generation of interim fluid layers during phase conversion in gas-ice system is indicated. The issues of generation of adjusted structure of surface monomolecular layer of water on self-arrangement capacity of water as an open thermodynamic system and on principles of unbalance theory. It was indicated that structural composition of monomolecular surface of water is similar to structural composition of hydrate network without absence of gas and that structural composition is linked to generation mechanism of crystal centers of hydrate. Crucial role of surface monomolecular layer of water in generation of crystal germs of hydrates and their growth process is indicated.
