Abstract

έθοδος δια την σύνθεσιν ουρίας περιλαμβάνουσα : την μετατροπήν της NR3 και CO2 της τροφοδοτήσεως προς ουρίαν και Η2C υπό πίεσιν της συνθέσεως και ειςθερμοκρασίαν, περιλαμβανομένην μεταξύ 190 βαθμών και 210 βαθμών C, της ρηθείσης μετατροπής ούσης, μερικής ή ολικής λόγω του γεγονότος της παρουσίας, υπό την πίεσιν και την θερμοκρασίαν της συνθέσεως,ενός μίγματος ανακυκλοφορίας συνισταμένου εκ καρβαμιδικού αμμωνίου, περισσείας αμμωνίας και ύδατος εις καταλλήλους αναλογίας.A method for the synthesis of urea comprising: converting NR3 and CO2 of the feed to urea and H2C under pressure of synthesis and at a temperature of between 190 degrees and 210 degrees C, said conversion of substance, partial or total, due to the presence of the pressure and temperature of the composition, a recirculation mixture consisting of ammonium carbamate, excess ammonia and water in appropriate proportions.
