Abstract (en)
[origin: WO2018007312A1] Device and process for producing an aqueous solution of urea. The production device comprises: - at least one device (26) for dissolving solid urea in demineralized water, comprising a tank (42) for receiving the solid urea and the demineralized water and an outlet (62) for recovering the aqueous solution of urea, - a solid urea storage station (2), - a device (14) for transporting the solid urea from the storage station (2) to the dissolving device (26), said transporting device (14) being arranged in order to pour solid urea into the tank (42) of the dissolving device (26). The dissolving device (26) comprises at least one nozzle (54) for injecting demineralized water into the solid urea, arranged in the vicinity of the bottom of the tank (42) in order to create water turbulence below the surface of the solid urea and to dissolve the solid urea in the demineralized water.
