Abstract
UN ADUCTOR CRISTALINO DE ALTA PUREZA DE BISFENOL A Y DE FENOL SE PRODUCE MEDIANTE LA CRISTALIZACION MULTIETAPA DE UNA PASTA FENOLICA DE BISFENOL A CON UNA SEPARACION DE CRISTAL Y UN PASO DE LAVADO QUE SE INTERPONE ENTRE CADA UNA DE LAS DOS ETAPAS. CADA ETAPA DE CRISTALIZACION INCLUYE UNA SERIE DE TORRES DE CRISTALIZACION QUE FUNCIONAN A TEMPERATURAS REDUCIDAS. LA CRISTALIZACION DE LA PASTA SE REALIZA MEDIANTE LA DESCARGA CONTINUA DE UNA PARTE DE LA PASTA DE CADA UNA DE LAS TORRES DE CRISTALIZACION, INTRODUCIENDO LA PASTA DESCARGADA DENTRO DE UNO O MAS REFRIGERADORES Y POSTERIORMENTE RECICLANDO LA PASTA REFRIGERADA HASTA LA TORRE. OTRA PARTE DE LA PASTA EN CADA PASTA DE CRISTALIZACION SE DESCARGA DE FORMA CONTINUA, SE CALIENTA PARA DISOLVER LOS CRISTALES FINOS DEL ADUCTOR Y POSTERIORMENTE SE RECICLA HASTA LA TORRE DE CRISTALIZACION DE FORMA QUE CREZCAN CRISTALES LARGOS EN CADA UNO DE LOS PASOS DE CRISTALIZACION. TAMBIEN SE PRESENTA UN APARATO QUE TIENE UNA PLURALIDAD DE REFRIGERADORES Y QUEES ADECUADO PARA EFECTUAR LA CRISTALIZACION DESCRITA.
