Abstract
Synthetic ammonia is used in the ammonia soda process, and the ammonium chloride liquor produced is not treated for the production of ammonia, but is evaporated to obtain a separation of sodium chloride at a high temperature, such as 100 DEG C. and then cooled to obtain a separation of ammonium chloride at a low temperature, the heating and cooling to obtain these salts being repeated if desired. The final mother-liquor, which is a cold solution saturated with ammonium and sodium chlorides, may be added to the liquor to be treated for the production of ammonium and sodium chlorides, as above described. It is stated that it is advantageous to oxidize a portion of the synthetic ammonia to nitric acid and to use some of the bicarbonate or soda obtained from it to absorb the acid.ALSO:Synthetic ammonia is used in the ammonia-soda process, and the ammonium chloride liquor produced is not treated for the production of ammonia, but is evaporated to obtain a separation of sodium chloride at a high temperature, such as 100 DEG C., and then cooled to obtain a separation of ammonium chloride at a low temperature, the heating and cooling to obtain these salts being repeated if desired. The final mother-liquor which is a cold solution saturated with ammonium and sodium chlories, may be added to the liquor to be treated for the production of ammonium and sodium chlorides as above described. It is stated that it is advantageous to oxidize a portion of the synthetic ammonia to nitric acid and to use some of the bicarbonate or soda obtained from it to absorb the acid.
