Soft drink manufacturers adhere to strict water quality standards for allowable dissolved solids, alkalinity, chlorides, sulfates, iron, and aluminum. Not only is it in the interest of public health, but clean water also facilitates the production process and maintains consistency in flavor, color, and body.
• The caustic soda must usually be concentrated to 50% and the salt removed. Mercury cell process: • Sodium metal forms an amalgam at a mercury cathode . 7 • This sodium is then reacted with water to produce NaOH. Membrane cell process: • This process is similar to the diaphragm cell process.
Thus, the different salts in seawater will precipitate at different times, forming layers on the bottom of the evaporating pond. For seawater and many brines, the order of deposition is calcium carbonate, calcium sulfate, sodium chloride, magnesium sulfate, potassium magnesium chloride, and magnesium chloride.
flow control valve in the bicarbonate solution feed line if more or less solution is needed. The resin remains in the neutralizer long enough for even the HCl trapped in the resin pores to be neutralized. The neutralizer exit stream is a slurry containing 15.0 wt % CPVC in an aqueous sodium chloride solution at 90 ºC and pH = 7.

presents a process flow diagram of the sesquicarbonate process. Searles Lake Process At the North American Chemical Company facility at Searles Lake, complex brines are first treated with carbon dioxide gas in carbonation towers to convert the sodium carbonate in solution to sodium bicarbonate, which will precipitate under these conditions.
Sodium bicarbonate is produced on all continents of the world and the global number of production sites is estimated to be 30-50. The estimated total amount of sodium bicarbonate used in 2001 is 2 million tonnes. Sodium bicarbonate is used as animal feed additive, human food additive and it is used in pharmaceuticals.

Sodium chloride is commonly called rock salt/table salt. Salt is mostly produced by evaporation of seawater. Commercial salt is manufactured from rock salt, as well as from seawater and other natural and artificial brines.
However, about 70 % of the world production capacity of sodium carbonate is manufactured by the Solvay (ammonia soda) process, whereby ammonia is added to a solution of sodium chloride. Carbon dioxide is then bubbled through to precipitate the bicarbonate, NaHCO3.
· making of sodium carbonate by solvary process Sodium carbonate is known as washing soda or soda ash. It is commonly occurred as a crystalline heptahydrate which readily effloresces to form a white powder, the monohydrate.
