Gas hydrates: nanosized phases in the separation and purification of substances by crystallization

Structural features of the nanosized phases of gas hydrates are considered. Physicochemical models for the formation of these phases are analyzed. Mathematical models for high purification of gases by gas hydrate crystallization and an algorithm for calculations of the parameters affecting the purification efficiency are given. Procedures for calculations of the distribution coefficients of mixture components between phases during the formation of mixed gas hydrates are discussed. The bibliography includes 109 references.
