Abstract
Ammonia is produced in a reactoror, in which pseudoisothermal conditions can be approached by convective cooling of a reaction zone of the reactor by positioning at least a portion of the reaction zone in indirect contact with a flow of hot gas such as exhaust gasor preheated air. The hot gasmay be supplied from a fired heater, a boiler, a reformer, a process air preheat furnace, a gas turbine, or the like. The reactor converts a feed stream of a purge gasor syngas to ammonia. The method may be implemented in a primary synthesis loop (as at) or in a purge gas loopof a new ammonia plant, or by retrofitting an existing ammonia plant. Cooperatively installed with a primary ammonia synthesis loop, the reactor increases total ammonia production.
