A method of revamping an ammonia-urea plant wherein: A) the ammonia-urea plant which is revamped has the following features: the ammonia urea plant includes an ammonia section and a urea section, said ammonia section includes a front-end for generation of a makeup syngas from reforming of a hydrocarbon and an ammonia synthesis section where the makeup syngas is reacted to produce ammonia ammonia produced in the ammonia synthesis section, and at least part of the CO2 removed from the makeup syngas in the front-end, are fed to the urea section for use as starting material for the production of urea, the urea section includes a high-pressure urea synthesis section including at least a urea synthesis reactor, a stripper for removing unconverted ammonia and carbon dioxide from the reactor effluent, and a condensation stage arranged to condensate stripper vapours containing ammonia and carbon dioxide removed from the reactor effluent, the urea section further includes a recovery section for recovering unconverted ammonia and carbon dioxide from the solution effluent from the stripper, at a pressure lower than the urea synthesis pressure, the ammonia-urea plant also includes a steam network, including steam producers and steam users, and steam produced in the ammonia section is exported to the urea section and sent to at least one steam user in the urea section, the condensation stage of the high-pressure urea synthesis section is a steam producer in the steam network and produces low pressure steam at a first pressure using the heat of condensation of the stripper vapours, said low pressure steam being used internally in the urea section in one or more steam users of the urea section, and B) the revamping includes: the provision of an export of low pressure steam at a pressure not greater than 6 bar rel, preferably 2 to 6 bar rel, from the ammonia section to the urea section, for use in at least one steam user in the urea section.
