Book excerpt: This report presents a cost analysis of Urea production from ammonia and carbon dioxide. The process examined is similar to Saipem's (formerly Snamprogetti) self-stripping process. In this process, ammonia and carbon dioxide are reacted to form ammonium carbamate intermediate, which is converted to Urea. The non-converted carbamate is stripped from the Urea solution by excess ammonia and decomposed back to ammonia and carbon dioxide, which are recycled to the Urea synthesis. After concentration and prilling steps, Urea Prills are obtained as final product. This report was developed based essentially on the following reference(s): (1) "Urea," Ullmann's Encyclopedia of Industrial Chemistry, 2010 (2) "Urea," Kirk-Othmer Encyclopedia of Chemical Technology, 5th edition Keywords: NH3 Stripping, Self-Stripping, Fertilizers, Snamprogetti, Saipem, Urea Prills
