| Abstract: | The waste heat generated in electrolysis was calculated. The using amount of bittern, as a result of the rational reuse of the waste heat, was determined. A novel dechlorination tower and the supporting secondary dechlorination process were used to remove excess water from dilute brine, and thus the production of caustic soda totally from bittern was realized. A new method for the dewatering of sodium sulfate was used and thus the bottleneck problems in the production of caustic soda from bittern with a high sodium sulfate content were solved. |
