THE ENERGOTECHNOLOGICAL PLANTS ON NATURAL GAS WITH CO-GENARATION PLANT AND THERMAL PUMP FOR MANUFACTURE OF THE ELECTRIC ENERGY, LIQUID CARBON DIOXIDE AND GASEOSE NITROGEN

Abstract

The carbon dioxide need is increment. It can be receive from the flue gases formed after burning natural gas. The analysis shows, that is more favourable in co-generation plant working on natural gas, beginning to make the electric power and heat, and then to divide on carbon dioxide and nitrogen. At creation of such systems there are problems: products of combustion after co-generation plant contain of oxygen; the potential of received heat appears not sufficient for production carbon dioxide from a solution of an absorbent. It is offered to use, first, co-generation plants of new generation which allow to work with factor of surplus of air  = 1, second, increase of temperature potential of heat to carry out with the help of the thermal pump. It has allowed to creating independently and effectively working 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. Exergy efficiency complexes amount to 39 % that is a high parameter of their efficiency. The made complexes have antiemission effect.
