Abstract

Un método para re-mineralizar agua de proceso de una planta de desalinización de agua de mar que comprende las siguientes etapas: proporcionar un filtro (22) de ósmosis inversa que incluye una entrada (24) aguas arriba para agua de mar y una salida (26) aguas abajo para la fracción permeada; proporcionar una membrana (38) de transferencia de gases, incluyendo la membrana primeros y segundos canales de flujo (34, 36), teniendo cada canal de flujo extremos de aguas arriba y aguas abajo, proporcionándose agua de mar al primer canal de flujo (34) y suministrándose dicha fracción permeada al segundo canal de flujo (36), estando el extremo (44) aguas abajo del primer canal conectado a la entrada (24) del filtro de ósmosis inversa, añadir un ácido al extremo (42) aguas arriba del primer canal para producir una disolución acidificada de agua de mar, de manera que el ácido reacciona con bicarbonato (HCO3 -) presente en el agua de mar para producir gas de dióxido de carbono (CO2); hacer pasar el gas de dióxido de carbono (CO2) a través de la membrana, de modo que el gas de dióxido de carbono (CO2) se fije desde el primer hasta el segundo canal de flujo y se disuelva en la fracción permeada; añadir una base al extremo (48) aguas abajo del segundo canal de flujo, en el que el dióxido de carbono fijado (CO2) disuelto en la fracción permeada reacciona con la base para producir bicarbonato de calcio (Ca(HCO3)2), añadiéndose el bicarbonato de calcio (Ca(HCO3)2) producido a la fracción permeada para, de este modo, añadir dureza y alcalinidad al agua resultante (H2O).
