Abstract

SE DIVULGA UN PROCESO PARA LA RECUPERACIÓN DE PETRÓLEO Y GAS (10), EN DONDE EL AGUA DE PRODUCCIÓN RESULTANTE TIENE SÍLICE. EL PROCESO COMPRENDE ELIMINAR SÍLICE DEL AGUA DE PRODUCCIÓN EN DOS ETAPAS. EN LA PRIMERA ETAPA, SE INYECTA ÓXIDO DE MAGNESIO EN UN REACTOR DE DISOLUCIÓN DE MAGNESIO (18) Y SE MEZCLA CON EL AGUA DE PRODUCCIÓN PARA DISOLVER MAGNESIO. EL EFLUENTE DEL REACTOR DE DISOLUCIÓN DE MAGNESIO SE DIRIGE DEBAJO DE UN ABLANDADOR DE CAL CALIENTE (22) DONDE ELEVA EL PH ENTRE 10,0 Y 11,5. LA SÍLICE ES CO-PRECIPITADA CON HIDRÓXIDO DE MAGNESIO Y/O ADSORBIDA SOBRE PRECIPITADOS DE HIDRÓXIDO DE MAGNESIO.
