Abstract:
Disclosed is a method of making a granulate of a urea product comprising urea and a salt, such as urea ammonium sulfate, having a high content of the salt. The high content is such as to provide an amount of the salt above the limit of solubility of the salt in urea. The granulate of the invention is characterized by having a smooth surface, which, e.g. in the event of urea ammonium sulfate, is not normally the case for granulate having the aforementioned high ammonium sulfate content. According to the invention this is realized by dividing the feed liquids to granulation. This division is based on non-final granulation liquids of a sufficiently high content of the salt, and a final granulation liquid (determining the surface) having a salt content of below the solubility limit of the salt, or no salt at all. E.g. in the event of urea ammonium sulfate, the non-final granulation liquids possibly are a slurry of urea and more than 20 wt. % of ammonium sulfate. The final granulation liquid then has 0-20 wt. % of ammonium sulfate, i.e. below the solubility limit.

Claim (Index 7):
A urea ammonium sulfate granulate obtainable by the method according to  claim 1 .
