Abstract

METODO DE OBTENCION DE UN PAQUETE DE TELA METALICA DE CAPTACION PARA USO EN LA OXIDACION DE AMONIACO. CONSISTE EN FROMAR SEGMENTOS CON FORMA DE SECTOR CIRCULAR A BASE DE PLEGAR RADIALMENTE UN DISCO DE TELA METALICA DIVIDIDO EN N PARTES DIAMETRALMENTE, DE LAS CUALES N-1 SON IGUALES, Y DE MANERA QUE EL ULTIMO PLIEGUE SEA MAYOR QUE LOS N-1 ANTERIORES, PARA DOBLARSE POR SU BORDE SOBRE EL PAQUETE Y EFECTUAR LA FIJACION DEL MISMO. EL MATERIAL ES ACERO INOXIDABLE, Y SOBRE ESTE SOPORTE SE INTERCALAN UN CONJUNTO DE SEGMENTOS DE IGUAL FORMA, PERO REALIZADOS A BASE DE UN MATERIAL ABSORBENTE, COMO UNA ALEACION DE ORO-PLATINO.
