Description
Summary:•A novel multigeneration system driven by solar energy and natural gas is presented.•The proposed system features carbon capturing with producing ammonium bicarbonate.•Energy and exergy performance assessment approaches are implemented on this multigeneration system.•Some parametric studies are conducted. This paper introduces a new multigeneration gas turbine-supercritical carbon dioxide combined power cycle integrated with a solar-powered carbon capturing system to produce electricity, cooling effect, freshwater, and ammonium bicarbonate. This multigeneration system is analyzed using the first and second laws of thermodynamics to assess the system performance. The results of this analysis show that this integrated system is able to produce ammonium bicarbonate at a rate of 1.30 kg s−1, while producing 2,280 kW of electric power. The overall energy and exergy efficiencies of this integrated system are found to be 22.3%, and 11.9%, respectively. Then, some parametric studies are conducted to observe how this integrated system behaves under different operating conditions. One finding is that the solar irradiance affects the overall energy and exergy efficiencies considerably. Also, changing the isentropic efficiencies of the turbines in the system has more significant effects on the net electric power production than changing the isentropic efficiencies of the compressors.
