Abstract

UN PROCEDIMIENTO PARA LA ELIMINACION DEL OXIGENO DISUELTO DE UN MEDIO ACUOSO. EN UN SISTEMA DE GENERACION DE VAPOR DE AGUA SE AÑADE HIDRAZINA MEZCLADA PREVIAMENTE DE MODO INTIMO, HACIENDOLA PASAR A TRAVES DE UNA COLUMNA QUE CONTIENE PERLAS DE VIDRIO, EN EL MEDIO ACUOSO ANTES DE LOS CALENTADORES DEL AGUA DE ALIMENTACION Y, DESPUES DE PASAR A TRAVES DE LA BOMBA DEL CONDENSADO SE PONE EN CONTACTO A UNA TEMPERATURA DE 20 A 40JC Y PRESION ENTRE 3,5 Y 10,5 KG/CM CON PALADIO O PLATINO DISPERSADO SBRE UNA RESINA CAMBIADORA DE ANIONES A BASE DE POLIESTIRENO PARA QUE REACCIONE LA HIDRAZINA CON EL OXIGENO DISUELTO Y SE REDUZCA ESTE A UN VALOR INFERIOR A 10 PARTES POR MIL MILLONES.
