Systems and methods for the production of ammonia

Abstract

Systems and methods for ammonia synthesis integrating an ammonia absorption refrigeration cycle and an ammonia synthesis cycle. The ammonia synthesis cycle includes a multistage non-adiabatic reactor system formed of multiple non-adiabatic reactors for converting a synthesis gas containing hydrogen and nitrogen into ammonia. The ammonia is chilled and stored as a cold ammonia product. Lean solution from the ammonia absorption refrigeration cycle can be used as a heat exchange utility fluid for the reactors, and the refrigeration cycle can also be used to chill the ammonia from the synthesis cycle for cold storage. Almost all of the syngas is converted in a single pass through the multistage non-adiabatic reactor system, eliminating the need for recycle streams and associated energy consumption.
