Abstract

PROCEDIMIENTO PARA LA PREPARACION DE AGUA DE MAR.EL AGUA DE MAR PURIFICADA MECANICAMENTE (2) SE HACE PASAR A TRAVES DE UN INTERCAMBIADOR DE IONES (4) CARGADO CON MAGNESIO, DEBILMENTE ACIDO O A TRAVES DE UN INTERCAMBIADOR DE IONES (10) EN FORMA MIXTA SODIO-POTASIO, FUERTEMENTE ACIDO-SELECTIVO DE LOS ALCALINOTERREOS. A CONTINUACION SE HACE PASAR A TRAVES DE UN INTERCAMBIADOR DE IONES (16) CARGADO CON SODIO, FUERTEMENTE ACIDO. DESPUES SE HACE PASAR A TRAVES DE UN INTERCAMBIADOR DE IONES EN FORMA DE CLORURO, DEBILMENTE BASICO Y POR ULTIMO EL AGUA SE ENVIAA UNA INSTALACION DE EVAPORACION (18) O DE OSMOSIS INVERSA. PARA REDUCIR EL VALOR DEL PH, EL AGUA DE MAR SE COMBINA CON CO2 QUE SE ENVIA CON AYUDA DE UN DESGASIFICADOR (36) A UN PROCESO CICLICO.
