Abstract
Sustainable production presents a viable approach that provides an environmentally friendly and integrated method for polygeneration objectives. This method can make the most significant impact in improving the effectiveness of conventional power plants. Furthermore, using renewable energy sources to modify the configuration of conventional power plants is imperative for implementing this methodology. Therefore, the primary objective of this research is to suggest a new method for attaining sustainable production in a power plant by integrating an environmentally friendly multi-heat recovery system. This innovative system allows for the efficient use of the power plant's flue gas for a polygeneration process and a geothermal power plant. The integrated setup comprises various components such as a multi-effect desalination unit, a proton exchange membrane electrolyzer, a cooling and heating generation subsystem, a liquefied natural gas regasification unit, a geothermal-based subsystem utilizing a flash-binary geothermal power plant, a Kalina cycle, and a heating generation unit. The study simulates this process using Aspen HYSYS software and conducts a comprehensive energy, exergy, economic, and environmental analysis. According to the results, the assessment reveals that the total energy and exergy efficiencies amount to 64.82% and 88.57%, respectively. The energy cost index is recorded at 0.028 $/kWh, alongside a specific CO2 emission of 0.211 kg/kWh. This value shows a notable reduction of 59.33% compared to a system reliant on biomass fuel. Parametric assessments are additionally conducted, whereby variations in performance metrics are predicted to exhibit the process performance.
