How to increase Ammonia Plant Capacity

This paper investigates the technical and economical feasibility of several concepts for a 30 % capacity increase of an old ammonia plant. It shows an interesting way to overcome the limitations in the two most critical plant units: Reforming capacity is increased by a newly added autothermal reformer, while capacity is added to the ammonia synthesis by the Uhde Dual Pressure Process.
