Haber-Bosch process alternatives for the production of green ammonia

Junho 2024

This work focuses on the simulation with Aspen Plus V11 of a conventional Haber-Bosh (HB) and an absorbent-enhanced HB process (AE HB) to produce green ammonia. Both simulations can be divided into three separate parts, the hydrogen synthesis, through water electrolysis, the nitrogen production, accomplished with a cryogenic air separation unit, and the ammonia synthesis loop, which can be absorbent-enhanced or not. To evaluate the energy requirements of these production processes, an energy analysis was performed for each simulation and further heat integration was explored using Aspen Energy Analyzer.
