Abstract

Starting from a synthesis process for ammonia in which converter parts heated in the process by the hot gas are cooled by colder gas, a solution is provided which in particular makes possible thinner-walled components and/or less expensive material for the converters and other components. According to the process, this is achieved by repeatedly recirculating the process gas over the ammonia converter(s), separating the ammonia at the end of a cooling space as condensate and passing the fresh gas as cooling gas in the area of hot process gases without contacting the latter. The device having at least one converter and one heat exchanger is distinguished in that a second converter (3) is additionally provided essentially in a parallel arrangement to the first converter (2) with an intermediate steam generator (4) as a heat exchanger in the floor area of both converters (2, 3), a fresh gas supply being arranged as a cooling gas supply in an antechamber (12) of the heat exchanger (4) and a twin pipe connection (11) to the first converter being provided for rinsing a hot gas pipe (9) coming from the first converter (2). <IMAGE>
