| titleOfInvention | A kind of resource utilization method of industrial by-product sodium sulfate and sodium chloride |
| abstract | The invention discloses a resource utilization method of industrial by-product sodium sulfate and sodium chloride. The method comprises: reacting the by-product sodium sulfate with gas containing sulfur trioxide to prepare sodium pyrosulfate, and adding Equimolar by-product sodium chloride reacts at high temperature to obtain sodium sulfate product, and the tail gas obtained reacts with sulfur dichloride to synthesize thionyl chloride. The present invention has not been reported at home and abroad, belongs to the pioneering technology, solves the current problems of by-product sodium sulfate and sodium chloride accumulation, high cost of reuse, and converts low-value by-product sodium sulfate and sodium chloride into sustainable The high-value product for downstream production has truly realized the resource utilization of sodium sulfate and sodium chloride. The sodium sulfate content of the obtained product is greater than 97%, which meets the requirements of the national standard (GBT 6009‑2014) for Class II qualified products and can be used for downstream production , such as the production of sodium silicate, as a cement additive, etc.; the content of the obtained thionyl chloride is greater than 98.5%, and can also be directly used in the production of downstream products. |
