Soda Ash Plant

T-brine from the solar ponds is first converted to relatively insoluble sodium bicarbonate, by reacting it with carbon dioxide gas. The sodium bicarbonate crystals are then separated from the brine and purified by washing. Subsequently, the purified bicarbonate is converted back to sodium carbonate (soda ash) by heating and ash is finally compacted into dense granules so that it is easy to transport and handle.
