Download or read book Granulated Urea from Ammonia via Self-Stripping Process - Cost Analysis - Urea E21A written by Intratec and published by Intratec. This book was released on 2019-09-17 with total page 102 pages. Available in PDF, EPUB and Kindle. 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 granulation steps, Urea Granules 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 Granules
