Feasibility Study of Polygeneration Turbine Plants Based on Carbon Dioxide

Schemes of polygeneration plants based on carbon dioxide are presented, in which the energy source secondary resources and a gas turbine plant. These schemes make it possible to simultaneously produce electricity, heat, cold, liquid gaseous aggregate state, as well dispose part emitted into atmosphere, due its absorption from combustion products use for commercial technological purposes. The structure mathematical model program that has been developed exergetic analysis is presented. With help program, an was performed, units with different parameters front turbine, single double overheating were compared. electrical efficiency whole individual elements taken criteria be Polygeneration supercritical have greatest efficiency. A method calculating economic indicators makes take account influence cost various versions schemes, such internal rate return, net discounted income, static dynamic payback periods obtained. It established all variants acceptable efficiency, period proposed does not exceed 5 years, while return decrease by less than 22,8%.
