In contrast to conventional methods, hydrogen was generated via the water–gas shift reaction using water molecules rather than natural gas. Carbon monoxide and carbon dioxide, which are typically released as waste, were reincorporated into the process to enable recovery. Furthermore, the mass flow rates of non-utilizable molecules were converted into electrical energy through turbine systems, thereby enhancing overall process efficiency. Parametric analyses were carried out to investigate the influence of temperature and pressure on yield and conversion rates within the ammonia reactor. These analyses, supported by detailed graphical representations, revealed the pronounced effects of temperature and mass flow rate on process performance. The system was ultimately designed as a self-sustaining configuration that mitigates environmental impacts by transforming harmful by-products into usable electrical energy. Compared with conventional systems, the proposed design fulfills its energy requirements through internal recovery mechanisms and simultaneously reduces the carbon footprint by converting waste gases into electricity. Collectively, the study demonstrates a sustainable and efficient strategy for ammonia production, underscoring the critical role of energy recovery and environmental stewardship in industrial applications.}, number={2}, publisher={Ankara Yildirim Beyazit University}
