Abstract

PROCEDIMIENTO PARA REGULAR LA TEMPERATURA EN REACCIONES EXOTERMICAS POR RECALENTAMIENTO DE VAPOR DE AGUA. SE UTILIZA COMO MED IO DE REFRIGERACION VAPOR DE AGUA DE UN ACUMULADOR DE CALOR (4) DE PRESION CONSTANTE LLENADO CON AGUA HIRVIENDO. SE EXTRAE DESDE EL ACUMULADOR DE CALOR (4), A TRAVES DE LA TUBERIA (5), VAPOR SATURADO QUE SE RECALIENTA EN VARIAS SECUENCIAS (8) Y, A CONTINUACION, SE ENFRIA DE NUEVO EN ETAPAS DE REENFRIAMIENTO (9) DISPUESTAS EN EL ACUMULADOR DE CALOR.
