Abstract: |
|||
| This process uses mirabilite as raw materials, and a carrier is used in liquid-phase for circulating substitution. Huge high-temp calcining apparatus is not required because of no need of reducing calcination of coal, so benefiting low energy consumption and high utilization rate of raw material. | |||
