C F Braun Description of Ammonia Synthesis

There are several processes to produce ammonia synthesis gas. The C F Braun (now may be referenced as Kellogg) process is one of the most current and acceptable processes due to the fact that the natural gas feed is less expensive than hydrogen generated from coke and water. This process has several stages of reaction and catalytic conversion that make it more presentable to industry, which are discussed in further detail.

Therefore, two reactors are placed in parallel, and a recycle stream is introduced to help the single-pass conversion of approximately 25%. The ammonia that is formed is condenses and removed to an absorber, where the vaporized ammonia used as a refrigerant in the previous separator is recompressed to liquid ammonia. The gases that did not react are purged and sent back to the primary reformer.
