Systems and methods for producing ammonia and/or ammonia products. The ammonia and/or ammonia products can be produced by compressing a gas mixture comprising nitrogen, hydrogen, methane, and argon to produce a compressed gas mixture having a pressure of from about 1,000 kPa (130 psig) to about 10,400 kPa (1,495 psig). All or a portion of the compressed gas mixture can be selectively separated at cryogenic conditions to produce a first gas comprising nitrogen and hydrogen, and a second gas comprising methane, argon, residual hydrogen and nitrogen. At least a portion of the first gas can be reacted at conditions sufficient to produce an ammonia product.

High pressure cyrogenic process and system for producing ammonia products

Systems and methods for producing ammonia. The system can include a first shell having two or more discrete catalyst beds disposed therein, a second shell disposed about the first shell, a first heat exchanger disposed external to the first shell and in fluid communication therewith, a second heat exchanger disposed external to the second shell and in fluid communication therewith, and a flow path disposed within the first shell. A first portion can be reacted in the presence of the catalyst to provide an ammonia effluent. The heat of reaction from the ammonia effluent can be exchanged within the first heat exchanger and the second heat exchanger. The heated second portion of the feed gas can be introduced to the first shell and can be reacted in the presence of the catalyst.
