titleOfInvention | Process for synthetizing urea from ammonia and carbon dioxide, with total carbon dioxide conversion |
abstract | A process for synthetizing urea by starting from NH₃ and CO₂, with total CO₂ conversion is disclosed which comprises:n (a) feeding, in countercurrent mode, to a reactive distillation column, NH₃ to the column bottom and CO₂ to the central column zone, with a liquid bottom stream being obtained which contains urea, NH₃ and water, and an overhead gas and/or supercritical stream constituted by NH₃ and water being obtained; (b) feeding the liquid stream coming from the bottom of the reactive distillation column to one or more separation steps, with NH₃ containing streams and an urea containing stream to be sent to a subsequent prilling step being obtained; (c) feeding the gas and/or supercritical stream coming from the reactive distillation column head, to a distillation column from the bottom of which water and from the head of which NH₃ are separated. |
