Pedchenko L. Theoretical and technological bases of transportation of gas hydrates in the thermal energy systems

The object is technology of the formation of hydrates of natural gas at different thermodynamic parameters; the purpose is creation of scientific basis of the energetically effective technology of the gas hydrate production in the form suitable for transportation and storage in non-equilibrium conditions by definition, research and substantiation of basic thermodynamic parameters; the method is experimental, theoretical, mathematical modeling, mathematical statistics; comparative analysis of data; the novelty - the first time physical and mathematical modeling of thermodynamic processes forced preserving samples of gas hydrate with the ice layer are implemented for determination of basic thermodynamic parameters of process of thermodynamic stabilization of the hydrate; the first time thermodynamic parameters of the process of the forced conservation of cooled hydrate are established and substantiated on condition prevention them dissociation at atmospheric pressure to establish operating modes storage of gas hydrates; the first time dependence of time of crystallization of water in the moistened layer from its thickness and the initial temperature of gas hydrates in the process of forced conservation are established; the thermodynamic parameters of stability and of controlled dissociation of the forced preserved gas hydrate blocks in temperatures above 273 K and atmospheric pressure are installed, which are the basis of technology of storage and transportation of gas hydrates; the results - the methods of formation and forced preservation of gas hydrate blocks with the ice layer are developed and substantiated on condition preventing of dissociation at atmospheric pressure; the method of production, the main technological parameters and principle scheme of the setting for the production of hydrocarbon gas hydrate are developed in a form that allows it storage, transportation and storage without additional cooling;degree of implementation - the obtained results are used at production and educational practice, that are confirmed by two acts of introduction; developed the complex of laboratory equipment was used at implementation of the two state budget scientific-research works of the Ministry of Education and Science of Ukraine for execution of scientific researches; branch - heat power engineering.
