What are the main components of the waste ammonia water in urea production? I seek advice from all the experts! Thank you!
The main components are: water (:lol), ammonia, CO2, and trace amounts of urea (if the system is not functioning properly and more emissions occur, the urea content increases sharply). ）
Thank you for the reply! In what form does CO2 exist inside? Ammonium bicarbonate? What other impurities might there be? Such as organic compounds of amines?
It mainly contains 7.9% ammonia and 1.2% urea. There is also a small amount of carbon dioxide, primarily in the form of methylammonium. The above values are theoretical; individual factories may experience deviations depending on operating conditions and the status of their equipment.
It’s mainly what the people above have said. If formaldehyde is added to your urea, there will still be trace amounts of formaldehyde; if there are problems with the surface cooler, then there could also be CL radicals and other substances.
