Abstract

UN PROCESO PARA LA PRODUCCION DE UREA EN EL QUE LA SOLUCION DE UREA PRODUCIDA EN LA ZONA DE REACCION SE TRATA EN SERIE CON UN PRIMER DESCOMPONEDOR TERMICO A LA MISMA PRESION QUE LA REACCION, PARA DESCOMPONER PARTE DEL CARBAMATO AMONICO RESIDUAL EN SUS COMPONENTES, A CONTINUACION CON UN SEPARADOR ADIABATICO EN EL QUE EL AMONIACO LIBRE SE SEPARA CON CO2 OPERANDO A UNA PRESION QUE ES DE 1-7 MPA MENOR QUE LA PRESION DE SINTESIS, A CONTINUACION CON DOS NIVELES COMPLEMENTARIOS DE DESCOMPOSICION TERMICA DEL CARBAMATO EN PRESIONES DECRECIENTES. LOS PRODUCTOS GASEOSOS OBTENIDOS DE ESTOS NIVELES EN PRESIONES MENORES QUE LA PRESION DE SINTESIS SE MEZCLAN CON LAS SOLUCIONES RECICLADAS DEL NIVEL DE AGUAS ABAJO, CONDENSADAS POR TRANSFERENCIA DE CALOR JUNTO A DICHOS NIVELES DE AGUAS ABAJO, Y POSTERIORMENTE SE RECICLAN PARA QUE REACCIONEN COMO UN LIQUIDO.
