Abstract:

This paper reviews currently industrialised low-pressure ammonia synthesis technologies (operating below 10 MPa synthesis pressure). Through process simulation calculations, it compares the power consumption per tonne of ammonia across different low-pressure ammonia synthesis technologies and analyses the cost per tonne of ammonia using ruthenium-based catalysts under the current pricing structure. It concludes by summarising the challenges and potential improvement directions for low-pressure ammonia synthesis technology.
