Abstract

EN UN PROCEDIMIENTO DE PRODUCCION DE UREA, SE HACEN REACCIONAR AMONIACO BASICAMENTE PURO Y DIOXIDO DE CARBONO, EN UN PRIMER ESPACIO DE REACCION, A PARTIR DEL CUAL SE GENERA UNA MEZCLA DE REACCION, QUE SE ENVIA A UNA SECCION DE RECUPERACION DE UREA. A PARTIR DE DICHA SECCION DE RECUPERACION SE OBTIENE UNA DISOLUCION DE CARBAMATO DILUIDA, QUE SE SOMETE A SU VEZ A EXTRACCION, RECICLANDOSE LOS VAPORES, TRAS SU CONDENSACION, HACIA UN SEGUNDO ESPACIO DE REACCION. DICHO PROCEDIMIENTO LOGRA UNA ELEVADA EFICIENCIA DE CONVERSION CON UN BAJO CONSUMO DE ENERGIA Y BAJOS COSTES DE PUESTA EN PRACTICA.
