( CO32- ) and hydroxide ions ( OH- ). The impurities are then filtered out.
The purified brine is then allowed to flow into the ammoniation tower, which contains ammonia gas (NH3). The ammonia gas dissolves in the brine to from ammoniated brine.
Stage 2- Carbonation of Ammoniated Brine
ln the second stage of the Solvay process, ammoninated brine from the first stage is pumped is the top of a tall carbonating tower, also know as a Solvay tower. the Solvay tower is fitted with numerous dome-shaped baffle plates, which break the ammoninated brine solution into a fine spray. This slows down the flow of the solution and increases the surface area where the reactions
