Expert Answer:

Essentially, this method involves saturating a concentrated brine solution with ammonia to form ammonium salts and then with carbon dioxide (made by burning lime). This produces ammonium bicarbonate, which reacts with the brine to form ammonium chloride and sodium carbonate. The sodium carbonate, in the presence of excess carbon dioxide, is converted to sodium bicarbonate, which precipitates out of solution and can easily be decomposed to soda ash by heating. The resulting carbon dioxide can be recycled, and the ammonium chloride treated to recover reusable ammonia.
