Device and process for producing an aqueous solution of urea

A device for producing an aqueous solution of urea from solid urea and demineralized water, of the type comprising:

• at least one device (26) for dissolving solid urea in demineralized water, in which the solid urea is dissolved in the demineralized water in order to form an aqueous solution of urea, said dissolving device (26) comprising a tank (42) for receiving solid urea and demineralized water and an outlet (62) for recovering the aqueous solution of urea,
• a solid urea (2) storage station,
• a device (14) for transporting solid urea from the storage station (2) to the dissolving device (26), said transporting device (14) being arranged to pour solid urea into the tank (42) of the dissolving device (26),
• wherein the dissolving device (26) comprises at least one nozzle (54) for injecting demineralized water into the solid urea poured into the tank (42), said nozzle (54) for injecting demineralized water being connected to a demineralized water source and being arranged in the vicinity of the bottom of the tank (42) in order to create water turbulence below the surface of the solid urea poured into the tank (42) and to dissolve the solid urea in the demineralized water so as to form the aqueous solution of urea.
