INTEGRATED PRODUCTION OF UREA FOR DIESEL EXHAUST FLUID AND UREA AMMONIUM NITRATE

Disclosed is a method for the integrated production of two different urea products. One is an aqueous urea solution suitable for use in NOx abatement (generally indicated as Diesel Exhaust Fluid - DEF). The other is a solution used as a fertilizer, viz. Urea Ammonium Nitrate (UAN). The production of...

Zusammenfassung:	Disclosed is a method for the integrated production of two different urea products. One is an aqueous urea solution suitable for use in NOx abatement (generally indicated as Diesel Exhaust Fluid - DEF). The other is a solution used as a fertilizer, viz. Urea Ammonium Nitrate (UAN). The production of DEF and UAN are integrated as follows: ammonia recovered from the production of urea is used as a feed to the production of ammonium nitrate. At least part of an aqueous urea stream from urea production, is mixed with ammonium nitrate so as to obtain UAN.
