EFFECTIVE MULTI-PURPOSE ENERGOTECHNOLOGICAL PLANTS ON NATURAL GAS FOR SYNCHRONOUS MANUFACTURE OF THE ELECTRIC AND THERMAL ENERGY, LIQUID CARBON DIOXIDE AND NITROGEN

Abstract

The carbon dioxide is advancing product which product from the flue gases formed after burning natural gas. The analysis shows that is more favourable in the beginning in co-generation unit working on natural gas, to make the electric power and heat. At creation of such systems there are problems: products of combustion after co-generation unit contain 8–10 % of oxygen; the potential of producible heat appears low. Some variants of elimination of the specified lacks are offered. It has allowed to creating independently and effectively working multi-purpose energotechnological plants using only natural gas, with the purpose of manufacture of electric and thermal energy, liquid low-temperature carbon dioxide and pure gaseous nitrogen. In these plants the high-energy potential of fuel is completely used.
