This master’s thesis investigates the optimization potential of green hydrogen integration into the ammonia synthesis process. Currently, the majority of hydrogen used in industry is produced from fossil fuel sources. As a result, increasing attention is being directed toward alternative technologies capable of reducing dependence on fossil energy resources while improving sustainability. The study examines green hydrogen production using a 200 MW alkaline water electrolyzer and evaluates the feasibility of integrating the produced hydrogen into the ammonia synthesis process. Particular attention is given to its influence on process stability, energy consumption, production efficiency, reduction of inert gas concentration in synthesis gas, and mitigation of carbon dioxide emissions. Simulation results indicate that the integration of green hydrogen into the process decreases CO₂ emissions from the combustion stream from 4.15 t/h to 2.92 t/h. In addition, the thesis includes financial and economic assessments, environmental considerations, occupational health and safety analysis, as well as proposed engineering and construction solutions. Based on the performed evaluations, the total project implementation cost is estimated at EUR 634.81 million, while the discounted payback period of the investment is projected to be 5.2 years. |
