METHOD FOR REMOVING SILICA FROM EVAPORATOR CONCENTRATE |
摘要 |
A method for removing silica from evaporator concentrate to facilitate disposal of the concentrate. An alkaline earth compound is mixed with the concentrate in a crystallizer. Silica in the concentrate reacts with the alkaline earth compound and precipitates from the concentrate as alkaline silicate complexes. The concentrate having the alkaline earth silicate complexes is directed to a separator where the alkaline earth silicate complexes are separated from the concentrate, producing an aqueous solution and slurry. The slurry is directed to a filter where solids are separated from a filtrate. Both the aqueous solution and the filtrate can be disposed of by deep well injection.
