Abstract

LA PRESENTE INVENCION, PROPORCIONA UN PROCEDIMIENTO DE OBTENCION DE UNA BREA DE MESOFASE MUY LIMPIA, A PARTIR DE BREA ISOTROPICA. LA INVENCION UTILIZA UN PROCEDIMIENTO DE FRACCIONAMIENTO POR SOLVENTE, QUE NO IMPLICA LAS FASES DE PROCESO, LA PERDIDA DE RENDIMIENTO Y LA PRODUCCION DE RESIDUOS, ASOCIADOS CON LA FUSION Y FILTRADO DE LA BREA ISOTROPICA. ADEMAS, LA INVENCION PROPORCIONA UN PROCEDIMIENTO DE EXTRACCION LIQUIDO/LIQUIDO, QUE EVITA LA MANIPULACION DE LOS SOLIDOS, Y LAS ALTAS TEMPERATURAS Y PRESIONES REQUERIDAS PARA LA EXTRACCION POR FLUIDOS SUPERCRITICOS. FINALMENTE, LA INVENCION CONTROLA LA DUREZA DEL PRODUCTO DE MESOFASE.
