Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO PARA SEPARACION DE FRACCIONES DE PLASTICO DE BAJA DENSIDAD, EN PARTICULAR DE UNA DENSIDAD POR DEBAJO DE 1 G/CM 3 , EN UN LIQUIDO UTILIZADO PARA EL INDICADO PROCEDIMIENTO, CUYA DENSIDAD PUEDE SER AJUSTADA POR MEDIO DE COMPONENTES DE MEZCLA DE DENSIDADES DIFERENTES. EL OBJETIVO DE LA INVENCION ES UNA SEPARACION ACEPTABLE ECONOMICAMENTE DE FRACCIONES DE ALTA CALIDAD, EN PARTICULAR DE FRACCIONES PP Y PE, EN CONDICIONES DE TRABAJO Y SEGURIDAD ACEPTABLES. PARA ESTE OBJETIVO EL PROCEDIMIENTO SE ORGANIZA DE TAL MODO, QUE EL LIQUIDO UTILIZADO SE OBTIENE MEDIANTE MEZCLA DE COMPONENTES DE DIFERENTES DENSIDADES, QUE PROCEDEN AL MENOS DE UNO DE LOS SIGUIENTES GRUPOS DE ESTERES SINTETICOS: A) ESTER DE PALMITADO (DENSIDAD MEDIA DE 0,86 G/CM 3 ), B) ESTER DE UNA MEZCLA DE ACIDO GRASO (DENSIDAD MEDIA DE 0,88 D/MG 3 ), C) ESTER METILO DE ACIDO GRASO (DENSIDAD MEDIA DE 0,93 G/CM SUP,3 , D) ESTER DE ACIDO DICARBOXILICO (DENSIDAD MEDIA DE 0,96 G/CM 3 .
