Haber-Bosch process alternatives for the production of green ammonia
Abstract
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.
Keywords: Haber-Bosch, green ammonia, water electrolysis, heat integration, Aspen Plus.
