The prill tower is part of the urea plant at the Ludwigshafen site

Urea (CH₄N₂O) is an organic compound of carbon dioxide (CO₂) and ammonia (NH₃). In 1968, the urea plant as it is known today was built. Urea is a versatile raw material and important monomer in the chemical industry. It is needed in large quantities worldwide, for example for the production of nitrogen fertilizer, for the exhaust gas purifier AdBlue^®, for resins, adhesives and much more. The 61-meter Prill tower, which is clearly visible from afar, is part of the urea plant built at the Ludwigshafen site in 1968. In it, crystalline urea is converted into spherical granules.
