Systems and methods to treat flue gas desulfurization and metal-bearing waste streams to recover value-added materials |
| abstract |
Disclosed herein are systems and methods from processing FGD gypsum feedstock and ash feedstocks, either separately or together. FGD gypsum conversion comprises reacting flue gas desulfurization (FGD) gypsum (calcium sulfate) feedstock, in either batch or continuous mode, with ammonium carbonate reagent to produce commercial products wherein the commercial products comprise ammonium sulfate and calcium carbonate. Ash conversion comprises a leach process followed by a precipitation process to selectively precipitate components at predetermined pHs resulting in metal hydroxides which may be optionally converted to oxides or carbonates. The processes may be controlled by use of one or more processors. |
