Abstract
Ammonia converter for radial flow through two catalyst beds has a central heat exchanger mounted centrally in one of the beds. The process stream of synthesis gas is obtained by combining inside the converter separate feed streams: a shell stream serving to cool the converter shell, an exchange stream serving to cool the central heat exchanger, and a by-pass stream for final adjustment of the temperature of the process stream. The process stream passes in succession radially through the first catalyst bed in inwards direction through the central heat exchanger for being cooled, and radially through the second catalyst bed.
