Abstract

PROCEDIMIENTO PARA EL ENFRIAMIENTO DE DISPERSIONES O LIQUIDOS EN CONEXION CON UNA DESODORIZACION MEDIANTE A) INTRODUCCION DE VAPOR DE AGUA A TRAVES DE UNA DISPERSION O LIQUIDO QUE SE VA A ENFRIAR Y QUE SE ENCUENTRA EN UNA CALDERA (1), LO CUAL HACE QUE ESTA SE ESPUME, B) SALIDA DE LA ESPUMA DESDE LA PARTE SUPERIOR DEL RECIPIENTE MEDIANTE UNA TOBERA (5) EN UN RECIPIENTE DE SEPARACION (4) DONDE LA ESPUMA SE ROMPE, C) CONDENSACION DE VAPOR DE AGUA FORMADO A PARTIR DE LA ESPUMA EN UN INTERCAMBIADOR DE CALOR (8) Y DE LLEGADA SIMULTANEA DE COMPUESTOS ORGANICOS EVAPORABLES, Y D) RECICLADO DE LA ESPUMA ROTA EN LA CALDERA (1). LA REALIZACION DE LAS ETAPAS A) A D) SE REALIZA HASTA QUE LA DISPERSION O EL LIQUIDO SE DESODORICE TODO LO QUE SE QUIERA, DESPUES DE ACABAR LA DESODORIZACION (SEGUN LAS ETAPAS A) A D)) SE LLEVA LA DISPERSION O LIQUIDO CALIENTE DESDE LA ZONA INFERIOR DE LA CALDERA (1) A TRAVES DE LA TOBERA (5) AL RECIPIENTE DE SEPARACION (4), DE TAL MANERA QUE LA DISPERSION O EL LIQUIDO SE ENFRIAN, UTILIZANDOSE LA TOBERA (5) Y EL RECIPIENTE DE SEPARACION (4) TAMBIEN PARA LLEVAR A CABO LA ETAPA B), QUE EL VAPOR DE AGUA QUE SE ENCUENTRA EN EL RECIPIENTE DE SEPARACION (4) SE CONDENSA EN EL INTERCAMBIADOR DE CALOR (8), QUE TAMBIEN SE HA UTILIZADO ANTES EN LA ETAPA C), Y QUE LA DISPERSION O LIQUIDO ENFRIADO SE SACA DEL FONDO DEL RECIPIENTE DE SEPARACION (4).
