Treatment of brine to remove metals and silicon therefrom |
摘要 |
Disclosed is a process for reducing the amount of silicon in brine. More specifically the silicon content of the brine is reduced to 1 ppm or less by using low caustic excess. The disclosed process can also be characterized as lowering sodium hydroxide excess (caustic excess) while maintaining the sodium carbonate level thereby obtaining a brine with a low level of silicon. A further purification step employs a sludge blanket.
