Abstract

UN PROCEDIMIENTO PARA DSULFURAR GASES QUE CONTIENEN DIOXIDO DE AZUFRE, DONDE LOS GASES QUE CONTIENEN AZUFRE ESTAN EN CONTACTO CON UNA DISOLUCION ACUOSA DE HIDROXIDO DE MAGNESIO EN UN LAVADOR HUMEDO, DONDE SE FORMAN SULFITO Y BISULFITO DE MAGNESIO, UNA PARTE DEL MEDIO DE LAVADO CONSUMIDO SE SOMETE A OXIDACION PARA CONVERTIR EL SULFITO Y BISULFITO DE MAGNESIO EN SULFATO DE MAGNESIO, EL PRODUCTO OXIDADO SE PONE EN CONTACTO CON UNA PARTE DE CAL QUE CONTIENE MAGNESIO PARA OBTENER HIDROXIDO DE MAGNESIO Y SULFATO CALCICO, EL SULFATO CALCICO SE SEPARA DEL PRODUCTO RESULTANTE Y EL HIDROXIDO DE MAGNESIO SE RECICLA AL LAVADOR.
