Abstract

LA PRESENTE INVENCION SE REFIERE A UN APARATO PARA LA POLIMERIZACION EN FASE GASEOSA DE OLEFINA(S), QUE ESENCIALMENTE COMPRENDE UN REACTOR DE LECHO FLUIDIZADO Y AL MENOS UN CONDUCTO PARA EXTRAER EL POLIMERO QUE TIENE UNA VALVULA DE SEPARACION Y QUE CONECTA LA PARED LATERAL VERTICAL DEL REACTOR CON UNA TOLVA DE RETENCION, EN DONDE DICHO CONDUCTO SALE DE LA PARED LATERAL VERTICAL DEL REACTOR MIENTRAS ES DIRIGIDO HACIA ABAJO DE MODO QUE CADA PARTE DEL CONDUCTO ANTEDICHO FORME RESPECTO A UN PLANO HORIZONTAL UN ANGULO A QUE VA DE 35 (GRADOS) A 90 (GRADOS) . TAMBIEN SE REFIERE A UN PROCEDIMIENTO DE POLIMERIZACION CONTINUA EN FASE GASEOSA DE OLEFINA(S) EN UN REACTOR DE LECHO FLUIDIFICADO, QUE CONSISTE EN EXTRAER EL POLIMERO DE LA PARED LATERAL VERTICAL DEL REACTOR E INTRODUCIRLO EN UNA TOLVA DE RETENCION A TRAVES DE UN CONDUCTO DE EXTRACCION DE MODO QUE TODO EL FLUJO DEL POLIMERO POR EL CONDUCTO DE EXTRACCION TENGA LUGAR EN UNA DIRECCION DESCENDENTE QUE FORME EN RELACION A UN PLANO HORIZONTAL UNAINCLINACION CON UN ANGULO A AL MENOS IGUAL AL ANGULO DE REPOSO {BE} DEL POLIMERO Y NO SOBREPASE LOS 90 (GRADOS) . CON LA PRESENTE INVENCION SE MEJORA EL GRADO DE LLENADO DE LA TOLVA DE RETENCION Y SE REDUCE LA CANTIDAD DE GAS EXTRAIDO JUNTO CON EL POLIMERO.
