Abstract

PROCEDIMIENTO DE OBTENCION DE MELAMINA. CONSISTE EN LA CONVERSION DE UREA Y/O SUS PRODUCTOS DE DESCOMPOSICION TERMINEN EN UN LECHO LFUIDO DE CATALIZADOR EN PRESENCIA DE UNA MEZCLA GASEOSA QUE CONTIENE NH3 Y CO2. LA PRESION PARCIAL DEL AMONIACO EN EL LECHO ES AL MENOS 70 KPA. LA RELACION DE VOLUMEN DE NH3 Y CO2 QUE SE EMPLEA COMO GAS DE FLUIDIFICACION EN EL REACTOR DE MELAMINA CONSISTE EN 90 POR 100 EN PESO DE NH3 Y CO2. N
