OPERATION MODE OF INTEGRATED ELECTROTECHNOLOGIC PLANT Russian patent published in 1999 - IPC

FIELD: heat- and-power plants. SUBSTANCE: invention relates to methods for separating furnace gases and can be used for simultaneously producing heat, cold and electric power and also for producing liquid carbon dioxide in order, in particular, to prevent releases of carbon dioxide into atmosphere by way of pumping its mixtures with water into deep strata of earth's crust, for example, into sea ground and ocean shelf. Operation mode of plant includes generating compressed furnace gas in generator, cooling it in pressure economizer, removing drop moisture, cooling gas once more in cooling regenerator, and extending compressed gas in turboexpander and simultaneously cooling it to solid carbon dioxide formation temperature. Solid carbon dioxide is then separated in separator and loaded into liquefier wherein it is melted as follows: liquefier filled with carbon dioxide is sealed, connected to receiver to raise pressure, filled with warmed water, and resulting mixture is kept to melt carbon dioxide and further pumped into subterraneous strata, while gaseous carbon dioxide is displaced by water from liquefier into receiver. After that, receiver is shut off, liquefier unsealed to reduce pressure to its normal value, water is poured out and liquefier is refilled with solid carbon dioxide, and so on. EFFECT: enabled separation of solid carbon dioxide from compresses furnace gas mixture. 1 dwg
