Ammonia is one of the most important industrial chemicals and is expected to play an increasingly important role not only in fertilizer production but also as a potential energy carrier. However, the conventional Haber–Bosch process remains highly energy-intensive due to the severe operating conditions required for ammonia synthesis and the energy demand associated with cryogenic ammonia recovery. This thesis investigates the integration of a membrane-based ammonia separation unit into a conventional Haber–Bosch synthesis loop as a process intensification strategy. A detailed process model was developed in Aspen Plus® based on the Temkin–Pyzhev kinetic model for ammonia synthesis over an iron-based catalyst promoted with Al₂O₃ and K₂O.
