Abstract: The invention relates to a method for producing a urea solution with a target urea concentration using water flows recovered from the urea production process. At least part of the water flows recovered from the urea production process are only partially purified to produce the urea solution. The invention further relates to a process condensate treatment plant to implement the method for producing a urea solution with a target urea concentration, and a urea production plant comprising such process condensate treatment plant.
