Inventors include Pizzolitto Cristina; Biasi Pierdomenico; Benedetti Alberto; Alxneit Ivo; Ferri Davide; and Cambie Federico.
The application for the patent was published on June 19, 2026, under issue no. 25/2026.
Abstract: Use of Near Infrared (NIR) spectroscopy preferably Fourier Transform NIR spectroscopy for obtaining a NIR spectrum or NIR spectra for determination of one or more chemical species in one or more process stream(s) of a urea process said urea process comprising at least one from among a synthesis process an evaporation process a crystallisation process a waste water treatment process and/or a finishing process. In particular the urea process comprises a urea synthesis process by reacting carbon dioxide and ammonia. The chemicals involved in the synthesis such as ammonia carbon dioxide urea and biuret can be quantitatively determined by NIR spectroscopy and the synthesis process can be adjusted based on the determination. The invention relates also to a urea synthesis plant involving NIR spectroscopy.
