Abstract
Disclosed is a system for the production of urea ammonium nitrate (UAN), which is particularly suitable for processing relatively small ammonium nitrate waste streams into UAN. The system comprises a concentration for ammonium nitrate, a treatment section which allows recovering and recirculating nitrogen compounds entrained in vapor from the concentration section, and a pH control section allowing to adjust the pH of the processed ammonium nitrate waste stream to the extent necessary.
