Decarbonizing ammonia synthesis plants through retrofitting novel reformer technology.

ABSTRACT: Decarbonizing ammonia production is crucial for reducing industrial greenhouse gas emissions; however, steam methane reforming (SMR) remains the dominant, carbon-intensive pathway. This study proposes a retrofit strategy for large-scale ammonia plants (1,268 tons/day) by replacing the conventional reformer with an advanced dual-reactor system that enables CO₂ utilization and carbon valorization. The novel configuration co-produces synthesis gas and multi-walled carbon nanotubes (MWCNTs), integrating ammonia and CNT production in a single process. Aspen Plus simulations compare the baseline SMR process with the retrofitted configuration, assessing energy demand, feedstock consumption, CO₂ emissions, and economic performance. The retrofitted system achieves a 76% reduction in plan
