Abstract

Una unidad de mezclado para flujos gaseosos a diferentes temperaturas y, en particular, para reactores de síntesis heterogénea exotérmica, que comprende un espacio de aire (11) para la recoleccion de un flujo (A) de gas caliente, una abertura anular (12) para la salida del flujo (A) de gas caliente desde el espacio de aire (11) y un distribuidor (13) perforado para un flujo (B) de gas de enfriamiento y que está dispuesto por debajo del espacio de aire (11); se requiere de un espesor constante del espacio de aire (11) en correspondencia con la abertura anular (12) y de una relacion de entre 0.2 y 1 entre la anchura de la abertura anular (12) y el espesor del espacio de aire (11). La presente unidad de mezclado permite la compensacion de variaciones locales en la velocidad del flujo (A) de gas caliente que sale del espacio de aire (11).
