Cost-effective clean ammonia production using membrane-assisted autothermal reforming

Abstract Ammonia is a widely produced industrial chemical, primarily for use in the fertilizer industry. Recently, interest has also grown ammonia as carbon-free energy carrier because it easier to store and transport than hydrogen. However, from natural gas with considerable carbon footprint if CO2 not captured stored. This work therefore presents new production method based on membrane-assisted autothermal reforming (MA-ATR) hydrogen integrated capture. The MA-ATR reactor offers great process intensification benefits, leading efficiency gains well simpler cheaper plant. In base case, achieves 10.7% greater efficiency, 14.9% lower NH3 costs 16.5%-points avoidance conventional plant where compressed storage. economic advantage of increases higher prices, electricity membrane prices. All elements proposed are mature technologies aside membranes oxygen material. Further development demonstration these two recommended realize promising techno-economic performance reported this study.
