Abstract

A radial ammonia converter system including first and second heat interchangers and first, second and third catalyst beds. The synthesis gas is heated in said first and second interchangers by catalyst bed effluent prior to full flow through each of the catalyst beds. In one embodiment, two of the catalyst beds are mounted with the first and second interchangers in one vessel; and in another embodiment, the first interchanger and second catalyst bed are mounted in one vessel and the second interchanger and first catalyst bed are mounted in a separate vessel. In both embodiments, the radial ammonia converter system is completed by a third catalyst bed in a separate vessel.
