PROCESS FOR PRODUCING AMMONIA

Abstract: a process for producing ammonia in an ammonia synthesis converter with co-production of steam from the recovery of process heat generated in the synthesis converter, the process includes producing power from expansion of said steam in a steam turbine which is mechanically coupled to a reversible motor/generator and to a compressor so to form an assembly which can be selectively operated in a first mode of operation and in a second mode of operation wherein: in said first mode, mechanical power is transferred from said steam turbine to said reversible motor/generator and to said compressor whilst in said second mode, mechanical power is transferred to said compressor from said steam turbine and from said reversible motor/generator.
