Abstract

La presente invención se refiere a un procedimiento continuo para controlar la contaminación en la preparación de fertilizantes que comprende hacer pasar una corriente que consiste esencialmente de aire y partículas de urea arrastradas hasta una zona de intercambio térmico de contacto directo, hacer pasar una segunda corriente de líquido en contracorriente con la misma de tal manera que una porción de los contaminantes de la primer corriente sea absorbida por la segunda corriente, el procedimiento está caracterizado por recircular la porción absorbida de la primera y la segunda de las corrientes en contacto de contracorriente con la primera corriente desde la zona de intercambio térmico en la zona de depuración de tal manera que se vaporiza agua exenta de contaminantes desde la porción absorbida de la primera y la segunda de las corrientes y los sólidos arrastrados son removidos de la segunda corriente, con lo que puede removerse vapor de agua y aire substancialmente puros y se produce una solución que contiene fertilizante la que puede ser utilizada en la fabricación del fertilizante.The present invention relates to a continuous process for controlling contamination in the preparation of fertilizers, comprising passing a stream consisting essentially of air and urea particles entrained into a direct contact heat exchange zone, passing a second stream of liquid in countercurrent with it in such a way that a portion of the contaminants in the first stream is absorbed by the second stream, the procedure is characterized by recirculating the absorbed portion of the first and second streams in contact with the countercurrent first stream from the heat exchange zone in the purification zone in such a way that contaminant-free water is vaporized from the absorbed portion of the first and second streams and the entrained solids are removed from the second stream, thereby Substantially pure steam and air can be removed and a solution containing fertilizer which can be used in the manufacture of the fertilizer.
