Abstract

PROCESO DE PRODUCCION DE UREA CON UNA ALTA EFICACIA ENERGETICA, EN LA QUE LA SOLUCION DE UREA OBTENIDA DE LA FASE DE SINTESIS SE SOMETE A UNA PRIMERA FASE DE DESCOMPOSICION TERMICA DE ALTA PRESION DEL CARBAMATO DE AMONIO QUE NO HAYA SUFRIDO LA CONVERSION A UREA JUNTO CON LA AUTODIVISION SIMULTANEA POR EL EXCESO DE AMONIO; LOS PRODUCTOS GASEOSOS DERIVADOS DE DICHA DESCOMPOSICION SE CONDENSAN EN DOS FASES A DISTINTAS TEMPERATURAS, EN LA PRIMERA DE LAS CUALES EL CALOR SE TRANSFIERE DIRECTAMENTE A UNA SEGUNDA FASE DE DESCOMPOSICION DEL CARBAMATO DE AMONIO QUE SE DIVIDE EN DOS PARTES, A SABER, UNA PRIMERA PARTE DE DESCOMPOSICION TERMICA Y UNA SEGUNDA PARTE CONSISTENTE EN LA DIVISION ADIABATICA CON PARTE DE LA ALIMENTACION DE DIOXIDO DE CARBONO DEL PROCESO.
