Abstract
EL OBJETIVO DE LA INVENCION LO CONFORMAN UN PROCEDIMIENTO PARA LA PRODUCCION DE OXIDO DE TITANIO MEDIANTE REACCION CON TICL SUB 4 EN FORMA DE VAPOR CON OXIGENO BAJO PRESION DE 2,4 A 3,4 BAR Y UN DISPOSITIVO CORRESPONDIENTE. EL OXIGENO NECESARIO SE CALIENTA INDIRECTAMENTE ENTRE 850 Y 1000 GRADOS C DE TEMPERATURA. LA CAMARA DE REACCION EN QUE SE CALIENTA ESTA CERRADA POR UN LADO Y ACONDICIONADA EN SU INTERIOR PARA UN FLUJO FAVORABLE DE GASES Y RESISTENTE EN PARTE AL FUEGO QUE SE CALIENTA A TRAVES DEL CONTACTO DIRECTO CON GASES MUY CALIENTES PROVENIENTES DE UN FUEGO AUXILIAR. SE CALIENTA HASTA TAL GRADO COMO SEA NECESARIO PARA UNA TRANSFORMACION ESPONTANEA CON EL TICL SUB 4 INTRODUCIDO, CORRIENTE ABAJO, EN LA CAMARA DE REACCION. AL MISMO TIEMPO, EL OXIGENO CALENTADO INDIRECTAMENTE SE DIFUNDE INMEDIATAMENTE EN EL LADO FRONTAL DE LA CAMARA DE REACCION A TRAVES DE UNA TOBERA ANULAR EN CUYO REVESTIMIENTO INTERIOR SE DISTRIBUYE HOMOGENEAMENTE EN TODO SU PERIMETRO EL OXIGENO QUE SE INTRODUCIRA EN LACAMARA. EL FLUJO DEL OXIGENO SE REGULA DE MODO QUE, EN LA TOBERA ANULAR, EL NUMERO REYNOLD OSCILA ENTRE 15000 Y 20000 Y LA RELACION DE DICHO NUMERO AL DIAMETRO INTERIOR DE LA CAMARA DE REACCION, MEDIDA EN MILIMETROS EN LA TOBERA ANULAR, VARIA ENTRE 25 Y 50. SE OBTIENEN TIEMPOS DE FUNCIONAMIENTO PERMANENTE MAS LARGOS.
