MOSCOW, 5 Jul. To predict the physical processes during the processing of gas hydrates, promising environmentally friendly energy resources, will allow a new approach of scientists from Tomsk Polytechnic University. According to them, the technique will significantly increase the efficiency of the use of these substances in the energy sector and other areas. The results are published in the International Journal of Heat and Mass Transfer.
Gas hydrates are ice-like crystalline compounds formed from water and gases at certain temperatures and pressures. In recent decades, they have been increasingly used as environmentally friendly fuels in energy and transport.
According to scientists, the use of natural gas hydrates has great potential, since their reserves are huge, and transportation is safer than in the case of liquefied gas. In addition, gas hydrates contain a lot of gas per unit volume — for example, in 1 cubic meter. m of methane hydrate contains up to 170 cubic meters. m of methane.
Scientists from Tomsk Polytechnic University, with the support of the Priority 2030 state program, have proposed a new approach to predicting the behavior of fuel from gas hydrates during refining. The method, according to the creators, is applicable both for the development of new power plants and for the selection of optimal hydrate combustion modes in existing systems. media-type=»ar16x9″ data-crop-ratio=»0.5625″ data-crop-width=»600″ data-crop-height=»338″ data-source-sid=»not_rian_photo» class=»» />< br />

«The characteristics of the decomposition of gas hydrates depend on a set of parameters: pressure and temperature, the size of the hydrate particles and its specific surface area, the type of an elementary crystal cell, the features of the interaction of gas and water molecules, and others. Our approach allows us to understand the physics of this process and give recommendations for managing it,” said Dmitry Antonov, Associate Professor of the Research School of Physics of High-Energy Processes at Tomsk Polytechnic University.
The method is also characterized by high calculation speed, scientists emphasized. In addition, as noted by university specialists, the approach allows working with hydrates of different origin, taking into account their structural features, determined by the climate of the region of formation. hydrates. >
