Latest Patents

Jan W Klok holds a patent for a method for making urea prills. This patent describes a process for producing urea prills by passing molten droplets of substantially water-free urea downwardly through a cooling zone, countercurrent to a cooling gas. The method maintains a dispersion of crystalline particles within the cooling zone, which improves the impact strength of the resulting urea prills. The crystalline particles have average dimensions between 2 and 10 microns and are dispersed in the cooling gas in a specific quantity, leading to the formation of prills built up of relatively small crystallites with random orientation.

Career Highlights

Jan W Klok is associated with Unie Van Kunstmestfabrieken B.V., where he has applied his expertise in chemical processes. His work has contributed to advancements in the production techniques used in the fertilizer industry.
