Requirements of Ashes recycling
System requirement
- The ashes recycling system shall be able to extract different metals from ashes.
Physical requirements
- In the column system, the rotator shall be able to mix the two phases well enough to transfer the metal ions from the aqueous phase to the organic phase.
- The mixer shall be able to dissolve all soluble in the ash.
Chemical requirements
- The column system shall be able to transfer the metallic salts from the solution to the solvent.
- The column material shall be able to withstand the corrosion with acid.
- In the column system, the rotator shall be able to mix the two phases well enough to transfer the metal ions from the aqueous phase to the organic phase.
- In the column system, the solvent used shall be able to extract a specific ion from the solution (e.g., LIX® 984N for copper ions).
- The mixer shall be able to dissolve all soluble in the ash into the acid.
- The pipes shall be able to withstand the corrosion with acid.
- The valves shall be able to withstand the corrosion with acid.
- The mixer shall be able to withstand the corrosion with acid.
Mechanical requirements
- The column shall be made of stainless.
- The mixer shall be rotate in 375 rpm in continuous and dispersed phase flow rate.
- The filter shall be able to avoid the solid particles to intel the column
- Time of soaking the ashes solution with acid shall be enough to dissolve all ashes in the acid solution.
- The material of pipes shall be made of PPR.
- The pumps shall be able to pump the liquids up to the column.
Automation requirements
- The sensors shall be able to control from the GUI.
- The valves shall be able to control from the GUI.
- The inflows and outflows of the fluids shall be able to harmonize with each other.
