Problem No. 22: How to strengthen prilled urea product
Approximately 75% of all urea plants worldwide still produce prills. Compared to granules, prills are smaller in size and have lower strength, leading to more dust problems during handling. Furthermore, prill strength is reduced, particularly during hot and humid weather conditions and when plant loads are increased. This Round Table discussion reports on the experiences of different plants and the solutions available to increase the strength of urea prills.
