Abstract: A method for revamping a self-stripping urea plant is disclosed, where an intermediate recovery section (30) is installed between the existing high- pressure section and medium-pressure section; a stream of urea solution (15A), which is delivered by the high pressure section, is directed to said intermediate section (30), and a flow of concentrated solution (15B) from said intermediate section is directed to said medium pressure section, the intermediate section operating at a pressure between those of the high- and medium-pressure sections. A related process and plant are also disclosed.
