Abstract

PROCEDIMIENTO PARA REDUCIR LA TENDENCIA A LA AGLOMERACION DE LA UREA. SE LE APLICA A LOS GRANULOS DE UREA UN TRATAMIENTO CON POLIALCOHILENGLICOL, REVISTIENDOLOS CON 0,1-0,3% EN PESO DE POLIALCOHILENGLICOL QUE TIENE UN PESO MOLECULAR DE 200 A 600 APROXIMADAMENTE. EL REVESTIMIENTO DE LOS GRANULOS PUEDE EFECTUARSE A TEMPERATURAS DE ENTRE 20 Y 75<025>C. EL REVESTIMIENTO PUEDE APLICARSE INMEDIATAMENTE DESPUES DE LA GRANULACION O TAMBIEN DESPUES DE QUE LOS GRANULOS SE HAN ALMACENADO DURANTE ALGUN TIEMPO EN EL SILO. LOS POLIALCOHILENGLICOLES QUE SE PUEDEN UTILIZAR PARA EL REVESTIMIENTO SON LOS FORMADOS A PARTIR DE MONOMEROS CON 2 A 5 ATOMOS DE CARBONO, Y PARTICULARMENTE POLIPROPILENGLICOL Y POLIETILENGLICOL.
