Abstract: |
The dense-slurry recovery technique for flue gas desulphurization by magnesia comprises: during the process, separating and leading out the dense slurry liquid, blasting air, heating and adjusting the temperature by steam to oxidize the MgSO3 dense slurry as one-time desulphurized product into MgSO4 with concentration achieved industrial level; filtering, crystallizing, and extracting the coarse grain MgSO4.7H2O. This invention is reliable with low cost and high value with the product, even has the yield effect super to industrial production for MgSO4. |
