Abstract

SE REFIERE A UN METODO PARA DIVIDIR UN FLUJO DE SOLIDOS A PARTIR DE UN CICLON, DE UN TANQUE FLUIDIZADO, O SIMILARES; EN DONDE EL FLUJO DE SOLIDOS ES DESCARGADO VIA UN PRIMER DOWNER Y ES FLUIDIZADO EN LA PARTE INFERIOR DEL PRIMER DOWNER MEDIANTE EL SUMINISTRO DE UN GAS TRANSPORTADOR, DE MODO QUE, POR LO MENOS UNA PARTE DEL FLUJO DE SOLIDOS ES TRANSPORTADA A LA PARTE SUPERIOR MEDIANTE DICHO GAS TRANSPORTADOR, VIA UNA PRIMERA TUBERIA ASCENDENTE QUE SE BIFURCA A PARTIR DEL DOWNER, Y DONDE LA PARTE RESTANTE DEL FLUJO DE SOLIDOS ES DESCARGADA, VIA UN SEGUNDO DOWNER, Y ES FLUIDIZADA EN LA PARTE INFERIOR DEL SEGUNDO DOWNER MEDIANTE EL SUMINISTRO DE UN GAS TRANSPORTADOR Y, POR LO MENOS, UNA PARTE DEL FLUJO DE SOLIDOS ES TRANSPORTADA A LA PARTE SUPERIOR POR EL GAS TRANSPORTADOR, VIA UNA SEGUNDA TUBERIA QUE SE BIFURCA A PARTIR DEL SEGUNDO DOWNER. SE DEFINE ADEMAS, UN APARATO QUE COMPRENDE UN PRIMER DOWNER PARA TRANSPORTAR UN FLUJO DE SOLIDOS, UNA PRIMERA TUBERIA ASCENDENTE QUE SE BIFURCA DEL PRIMER DOWNER, UN PRIMER SUMINISTRO DE GAS TRANSPORTABLE, UN SEGUNDO DOWNER QUE UNE EL PRIMERO DEBAJO DE LA FLUIDIZACION, UNA SEGUNDA TUBERIA ASCENDENTE QUE SE BIFURCA DEL SEGUNDO DOWNER Y UN SEGUNDO SUMINISTRO DE GAS TRANSPORTADOR, MEDIANTE EL CUAL, EL GAS SE INTRODUCE DENTRO DE DICHO SEGUNDO DOWNER, A FIN DE TRANSPORTAR LOS SOLIDOS A TRAVES DE LA SEGUNDA TUBERIA
