Opis:
The technology of development of bottom gas-hydrate deposits, which allows to receive fresh water simultaneously with methane, is presented. Principal schemes are presented and methods of operation of dualpurpose plants implementing this technology and described on the basis of the methods of gas production from methane hydrates that are most prepared for practical implementation: 1) injection of warm water into the well; 2) depressive effect on the deposit; 3) replacement of methane in hydrates with carbon dioxide injected into the reservoir. The magnitude of the decrease in temperature with the depression effect on the deposit is determined. It is shown that, the amount of fresh water obtained in dual-purpose plants operating with the replacement of methane in hydrates with carbon dioxide is proportional to the coefficient of the recycling rate of CO2. For the considered schemes of dual-purpose plants, processes of decomposition of methane hydrates in the gas-hydrate formation are analyzed, an exergic efficiency estimation is performed. Such installations. The economic efficiency of a single-purpose and dual-purpose gas-producing units operating according to an approved method of depression is considered. It is shown that the most effective are dual-purpose facilities operating using the method of methane replacement in hydrates with carbon dioxide, and the coefficients of economic efficiency of dual-purpose installations are at least 1.2 times higher than similar coefficients of single-purpose gas production facilities.

Opis:
Abstract Methane production from natural gas hydrates will enable the reduction of a great part of natural gas import deliveries and to give up them completely in the future. Gas hydrate technologies compared with existing ones, also gives the possibility to transport gas, divide gas and liquid mixtures, concentrate water solutions, utilize and store СО2, etc. with greater efficiency. However, methane production technologies have not developed industrially and their study was performed with the help of experimental units and in separate gas hydrates deposits in the mode of tests and elaborations. The prospects of the hydrate technologies development in the Ukraine were determined: transportation of natural gas in the form of hydrates, long-term storage of natural gas in hydrate state, natural gas production from its hydrate deposits. Positive international experience in terms of the development of hydrate technology is studied. In order to study formation and dissociation hydrates of carbon dioxide and natural gas components, Gas Institute have made hydrate stand facility. The express method of determining thermodynamic and kinetic parameters of hydrate transformation was tested. Natural gas hydrates as well as carbon dioxide hydrates were produced with the help of the express method. It was determined that the composition of original natural gas and gas of hydrates decomposition is of great difference – it means that “selective” hydrates formation of natural gas formation is performed.A set of experiments was also performed to study the process of methane replacement with the help of carbon dioxide. According to the gaseous phase analysis, 14% increase of methane content was fixed. This fact proves its replacement in hydrates with the help of carbon dioxide.

Opis:
It is well known that the most effective method of air distribution in high-heat areas is displacement ventilation with a variable air loss according to changeable operating conditions. Dense equipment arrangement makes requirements to air distribution even higher. The necessity of spreading jets till they reach convective flows is shown. To slow down these jets uniform air supply is required at the exit of an air distributor. Modern devices do not fully meet this requirement. The suggested method of air supply ensures uniform air distribution and thorough ventilation of the area at a changed expenditure of inflowing air.
Wiadomo, że najbardziej skutecznym sposobem nawiewu powietrza do pomieszczeń ze źródłami ciepła jest wentylacja wyciągowa ze zmiennym przepływem powietrza w zmiennych warunkach eksploatacyjnych. Zwiększanie szczelności pomieszczeń podwyższa wymagania do nawiewu powietrza. Aby zmniejszyć prędkość strumieni, należy zapewnić równomierny przepływ powietrza na wyjściu z jednostki nawiewu powietrza. Stosowane metody wentylacji na ogół nie spełniają tego wymogu. Zaproponowany sposób dopływu powietrza pozwala zapewnić równomierność dostarczania powietrza i likwidację nieprzewietrzanych stref przy zmianie wydatku przepływu powietrza.
