Phoenix Equipment Corporation has this used Ammonia plant immediately available. In the primary reformer, feed gas is mixed with steam, preheated by exchange with high temperature shift effluent, and then further heated in the reformer convection section. The effluent from the primary reformer and process air are mixed in the top of the secondary reformer. Conversion of the CO to CO2 in the reformed gas stream is achieved catalytically in ammonia converter. The synthesis stream leaving the shift converter contains carbon dioxide on a dry gas basis. It is necessary to remove all carbon dioxide from the synthesis gas before entering the ammonia synthesis loop.
