| Abstract: | The removal method of SO 2- 4 in production of calcium chloride from waste liquid of ammonia-soda process was studied in the paper.The test proved that the content of SO 2- 4 in waste liquid can be decreased to 0.02% by mixing concentrated calcium chloride liquid and waste liquid.Therefore,calcium sulfate scale on the evaporator wall in the subsequent evaporation was reduced. |
