Abstract

PROCESO CONTINUO PARA LA POLIMERIZACION EN FASE DE GAS DE UNA O MAS OLEFINAS CH{SUB,2}=CHR, QUE SE LLEVA A CABO EN UNO O MAS REACTORES DE LECHO FLUIDIFICADO QUE COMPRENDEN UNA ZONA DE POLIMERIZACION Y UNA ZONA DE REDUCCION DE LA VELOCIDAD DEL GAS COLOCADA ENCIMA DEL LECHO. EL REACTOR DE LECHO FLUIDIFICADO SE ENCUENTRA UNIDO A UN TUBO DE RECICLADO DEL GAS, QUE INCLUYE AL MENOS UN COMPRESOR Y AL MENOS UN DISPOSITIVO DE REFRIGERACION, MEDIANTE EL CUAL EL GAS QUE SALE POR LA PARTE SUPERIOR DEL REACTOR SE COMPRIME, REFRIGERA Y VUELVE A ENVIAR AL REACTOR EN UN PUNTO POR DEBAJO DE LA ZONA DE REACCION. EL PROCESO SE CARACTERIZA POR EL HECHO DE QUE EL MONOMERO O MONOMEROS DE RELLENO SON ENVIADOS DIRECTAMENTE AL REACTOR DE LECHO FLUIDIFICADO A UNO O MAS PUNTOS POR ENCIMA DEL LECHO FLUIDIFICADO.
