Abstract

LA INVENCION PROPORCIONA UN PROCESO PARA RECUPERAR POLIMEROS DE POLIESTER, PARTICULARMENTE TEREFTALATO DE POLIETILENO (TEP) DE UNA CORRIENTE DE RECIRCULACION DEL POLIMERO MIXTO, TIPICAMENTE EN FORMA DE BEBIDA SIN ALCOHOL CARBONATADA U OTROS ENVASES. ESTE PROCESO CONSTA DE : (1) PONER EN CONTACTO LA CORRIENTE DE RECIRCULACION DEL POLIMERO MIXTO CON UN DISOLVENTE QUE DISUELVE EL POLIESTER SELECTIVAMENTE, (2) SEPARANDO DEL DISOLVENTE SELECTIVO QUE CONTIENE TEP DEL POLIMERO MIXTO RESIDUAL, (3) ENFRIANDO EL DISOLVENTE SELECTIVO PARA PRECIPITAR EL POLIESTER, Y (4) SEPARANDO EL POLIESTER RECUPERADO DE ESTA FORMA. EN UNA VERSION PREFERIDA, LA CORRIENTE DE RECIRCULACION DEL POLIMERO MIXTO ES QUIMICAMENTE LAVADA POSTERIORMENTE A SU LAVADO Y ANTES DEL CONTACTO CON EL DISOLVENTE SELECTIVO. EL POLIESTER RECUPERADO ES COMBINADO PREFERENTEMENTE CON UN POLIESTER "VIRGEN" Y PROCESADO ADEMAS PARA AUMENTAR SU PESO MOLECULAR.
