A process for the synthesis of ammonia from a hydrocarbon feedstock, wherein the process includes reforming the hydrocarbon feedstock to produce a make-up gas and converting said make-up gas into ammonia, the process is performed in an ammonia synthesis plant requiring an electric power for operation and also requiring a start-up power (Ps) for start-up, wherein a first electric power (P1) is internally produced in the ammonia plant, and a second electric power (P2) is imported, wherein said second electric power is equal to or greater than said start-up power (Ps).

Process for the synthesis of ammonia

A method for revamping an ammonia plant including a steam system, said steam system comprising at least a high-pressure section operating at a first pressure and a medium-pressure section operating at a second pressure lower than said first pressure, the revamping including: the provision of at least one additional heat recovery by means of a steam flow at a third pressure which is intermediate between said first and second pressure, and the provision of a steam export line arranged to export outside the ammonia plant at least a portion of said steam flow at said third pressure.
