Abstract
Procedimiento de rendimiento mejorado para la síntesis de urea a partir de amoníaco y dióxido de carbono, comprendiendo una zona de reacción bajocondiciones de alta presión y temperatura, una sección donde una porción de amoníaco y dióxido deca rbono son exhaustados y reciclados al reactor, cuyassecciones operan bajo sustancialmente la misma presión del reactor, y una sección subsiguiente, operando bajo condiciones de media y/o baja presión, parala purificación de urea ysimultánea re cuperación de dióxido de carbono residual y una porción del amoníaco residual contenido en la corriente efluentedesde la sección de exhaustación, en tanto una solución acuosa de carbamato de amonio efluente de la etapa deseparación (P) es r ealimentada a dicha secciónde exhaustación. Dicho procedimiento hace posible que la cantidad de agua alimentada al reactor disminuya significativamente obteniéndose una conversiónde dióxido de carbono a urea a ser obtenidaen el reactor la cual es mayor que el 70%.Improved performance procedure for the synthesis of urea from ammonia and carbon dioxide, comprising a reaction zone under high pressure and temperature conditions, a section where a portion of ammonia and carbon dioxide are exhausted and recycled to the reactor, whose sections operate under substantially the same reactor pressure, and a subsequent section, operating under medium and / or low pressure conditions, for purification of urea and simultaneous recovery of residual carbon dioxide and a portion of the residual ammonia contained in the effluent stream from the section of exhaustion, while an aqueous ammonium carbamate solution effluent from the separation stage (P) is fed back to said exhaustion section. Said procedure makes it possible for the amount of water fed to the reactor to be significantly reduced obtaining a conversion from carbon dioxide to urea to be obtained in the reactor which is greater than 70%.
