Abstract

1. UN APARATO DE DESVOLATILIZACION DE POLIMEROS MEJORADA COMPRENDE UN CALENTADOR DE PLACA PLANA QUE COMPRENDE UN MEDIO DE SUMINISTRO DE SOLUCION DE POLIMERO, Y UN MEDIO DE SEPARACION Y RECOLEC- CION DE LIQUIDO/VAPOR, DICHO CALENTADOR DE PLACA PLANA COMPRENDE ADICIONALMENTE UNA MULTIPLICIDAD DE PLACAS PLANAS QUE DEFINEN UNA PLURALIDAD DE CANALES, CADA CANAL TENIENDO UNA ALTURA UNIFORME SUSTANCIALMENTE PERO VARIANDO EN SU ANCHO A LO LARGO DE LA LONGITUD TOTAL DEL CANAL, CADA CANAL COMPRENDE TRES ZONAS: UNA PRIMERA ZONA, QUE TIENE UN INICIO Y UN FINAL, DICHO INICIO ESTA EN COMUNICACION OPERATIVA CON LOS MEDIOS DE SUMINISTRO DE SOLUCION DE POLIMERO, CARACTERIZADO POR SU ANCHO DECRECIENTE EN FUNCION DE LA DISTANCIA DESDE SU INICIO, UNA SEGUNDA ZONA QUE TIENE UN INICIO EN EL FIN DE LA PRIMERA DE LA ZONA Y UN FINAL, CARACTERIZADO PORQUE AL MENOS EXISTE UNA OCURRENCIA DE UN AREA DE SECCION TRANSVERSAL RESTRICTIVA, Y UNA TERCERA ZONA QUE TIENE UN INICIO AL FINAL DE LA SEGUNDA ZONA Y TERMINA EN UNA REGION DE SEPARA- CION Y RECOLECCION DE LIQUIDO/VAPOR OPERANDO A PRESION REDUCIDA, DICHA TERCERA ZONA ESTA CARACTE- RIZADA POR SU ANCHO INCREMENTAL COMO FUNCION DE LA DISTANCIA DESDE SU INICIO, Y SIEMPRE QUE ADICIO- NALMENTE SU RADIO SU PROPORCION DE ANCHO MAXIMO DE LA TERCERA ZONA AL ANCHO MAXIMO DE LA SEGUNDA ESTE ENTRE 2:1 A 20:1.
