Abstract

SE REFIERE A UN PROCESO QUE COMPRENDE INTRODUCIR UNO O MAS MONOMEROS, DE PREFERENCIA ETILENO, PROPILENO Y EN FORMA OPCIONAL UN ALCANO INERTE, EN POR LO MENOS DOS ZONAS DE POLIMERIZACION INTERCONECTADAS EN PRESENCIA DE UN CATALIZADOR EN CONDICIONES DE REACCION Y RECOGER EL PRODUCTO DE POLIMERO DE DICHAS ZONAS DE POLIMERIZACION. LAS PARTICULAS DE POLIMERO EN DESARROLLO FLUYEN HACIA ARRIBA A TRAVES DE UNA DE DICHAS ZONAS DE POLIMERIZACION (COLUMNA DE SUBIDA) BAJO FLUIDIZACION RAPIDA O CONDICIONES DE TRANSPORTE, DEJAN LA COLUMNA DE SUBIDA E INGRESAN A OTRA ZONA DE POLIMERIZACION (COLUMNA DE BAJADA) POR DONDE FLUYEN HACIA ABAJO POR GRAVEDAD, DEJAN LA COLUMNA DE BAJADA Y SE VUELVEN A INTRODUCIR EN LA COLUMNA DE SUBIDA. ADEMAS SE INTRODUCE A TRAVES DE UNA O MAS LINEAS DE ALIMENTACION DE LA COLUMNA DE BAJADA UNA MEZCLA GASEOSA Y/O LIQUIDA (TOTAL O PARCIALMENTE LICUADA), CUYA COMPOSICION ES DIFERENTE A LA DE LA MEZCLA DE GAS PRESENTE EN LA COLUMNA DE SUBIDA, PARA EVITAR QUE LA MEZCLA GASEOSA INGRESE EN LA COLUMNA DE BAJADA Y ESTABLECIENDO UN FLUJO NETO DE GAS HACIA ARRIBA EN EL LIMITE SUPERIOR DE LA COLUMNA DE BAJADA
