Abstract
PROCEDIMIENTO Y APARATO PARA LA CONCENTRACION DE SOLUCIONES ACUOSAS DE GLICOLES. EL PROCEDIMIENTO CONSISTE EN HACER EVAPORAR LAS SOLUCIONES ACUOSAS EN UNA SERIE DE EVAPORADORES DE PELICULAS VERTICALES APROVECHANDO EL PRINCIPIO DE DESTILACION DE EFECTOS MULTIPLES. LA CONCENTRACION DE LAS SOLUCIONES DE GLICOLES SE EFECTUA A PRESIONES COMPRENDIDAS ENTRE 20 Y 0,03 KG/CM Y A TEMPERATURAS QUE VAN DE 200 A 30 C. EL APARATO COMPRENDE LOS SIGUIENTES ELEMENTOS: 1 ) AL MENOS UN EVAPORADOR DE PELICULA. 2 ) AL MENOS UNA CUBETA. 3 ) UN SISTEMA DE ESTANQUEIDAD Y DE REGULACION DEL CAUDAL DISPUESTO EN EL FONDO DE CADA CUBETA. 4 ) ABERTURAS PRACTICADAS EN EL LATERAL DE CADA CUBETA. 5 ) AL MENOS UN TUBO DE SIFON PARA TRANSFERIR EL CONDENSADO AL TRAMO SUCESIVO.
