Problem No. 4: Gaseous ammonia and dust emissions in urea plants

The urea industry continuously strives to reduce ammonia and urea dust emission from urea plants. The European Fertilizer Manufacturers’ Association has described the Best Available Technologies for emission reduction; please refer to “Best Available Techniques for Pollution Prevention and Control in the European Fertilizer Industry, Booklet No. 5 of 1: Production of Urea and Urea Ammonium Nitrate, 2000” which one can be downloaded from their website (http://www.efma.org). The aim of this round table discussion is to collect the different solutions actually applied in urea plants to reduce gaseous ammonia and urea dust emissions.
