Abstract

UN SISTEMA PARA AUMENTAR EL RENDIMIENTO Y AL MISMO TIEMPO EL POTENCIAL DE PRODUCCION DE LOS REACTORES PARA UREA, FORMADOS MEDIANTE LA SINTESIS DE AMONIACO CON DIOXIDO DE CARBON A ALTA PRESION Y TEMPERATURA, EL ESPACIO INTERNO DE DICHOS REACTORES (R) SIENDO TRASPASADO PARALELAMENTE POR UNA FASE LIQUIDA Y UNA FASE GAS Y SIENDO DIVIDIDO EN COMPARTIMENTOS (C SUB 1 3), PARA EVITAR LA MEZCLA EXCESIVA DE LA FASE LIQUIDA INTEGRA Y PARA PERMITIR LA REDISTRIBUCION INTERMITENTE DEL GAS EN BURBUJAS DE UN TAMAÑO ADECUADO PARA AUMENTAR EL INTERCAMBIO DE CALOR Y MATERIA ENTRE LAS DOS FASES. CARACTERIZANDOSE POR EL HECHO DE QUE EN CADA PASO DE UN COMPARTIMENTO AL SIGUIENTE SE HACE FLUIR A LA FASE LIQUIDA Y FASE GAS SOBRE RUTAS SEPARADAS Y DISTRIBUIRSE CADA UNA CON UN FLUJO CONTINUO, PERMANENTE Y CONSTANTE.
