Abstract

Los precalentadores para calentar soluciones de polímeros provenientes de reactores de polimerizacion antes de la desvolatilizacion al vacío son bienconocidos en el arte. Sin embargo, no se conocen dispositivos precalentadores para la desvolatilizaci on de polímeros, ni la metodología necesaria para encararlos problemas que se encuentran durante el uso de los dispositivos del arte anterior. En particular, se trata de lograr un precalentador y una metodologíamediante la cual el costo del equipo, l a caída de la presion, el tiempo de residencia, la mala distribucion de la temperatura y la inestabilidad del caudal seminimizan en su totalidad. Precalentador de desvolatilizacion de polímeros y método para utilizar el mismo para precalentar la solu cion polímero/solvente. Elprecalentador incluye un recipiente alargado, hueco y recto que define a la cámara de calentamiento con extremos superior e inferior, así como a un ejelongitudinal que se extiende entre los extremos. Existe una entrada de so lucion polímero/solvente ubicada en forma adyacente al extremo superior de la cámara yuna salida de polímero fundido emplazada en forma adyacente al extremo inferior de la cámara. Existe una pluralidad de manojos de tubos de calentamientomontados en la cámara, incluyendo, cada manojo, una pluralidad de tubos de calentamiento de serpentina alargados que se encuentran dispuestos, cada uno, en unaconfiguracion tal que su eje principal se extiende a través de la cámara en una direccion transversal a l eje longitudinal del recipiente. Los tubos seencuentran posicionados de tal manera que la solucion polímero/solvente se ponga en contacto de transferencia de calor con la superficie externa de los mismosa medida que la solucion polímero/solvente fl uye a lo largo del trayecto que se extiende desde la entrada de la solucion polímero/solvente hacia la salida delpolímero. Cada tubo comprende una pluralidad de porciones de tubos curvados y una serie de porciones de tubos de enlace que interconectan las porciones detubos curvados. Las porciones de tubo de cada uno de ellos se encuentran dispuestos en un plano comun que está emplazado en forma sustancialmente paralela con
