Abstract

The actual problem is increase of efficiency and decrease of power consumption by manufacture of liquid carbon dioxide. It is shown that the efficiency of production grows at reception except for СО2 and other products, for example, nitrogen, and also thermal and electric energy. The ways of modernization existing carbon dioxide units extracting СО2 from flue gases, formed after burning natural gas are considered. As a result of realization of the considered decisions the specific charge of the electric power can be lowered on 40 %. In existing units it is possible to achieve also decrease in the charge of natural gas to 30 % due to use of flue gases from other boiler units. A new energotechnological complexes using co-generation and steam-turbine units for manufacture of the electric power and heat are described. The exergy efficiency of such complexes exceeds 40 % that testifies to their high efficiency.
