AI Technical Summary
Technical Problem
Existing methods for recovering iodine from flue gas are inefficient and prone to salinization, limiting the concentration of iodide in scrubbing solutions, which hinders continuous recycling.
Method used
A method involving cooling iodine-containing flue gas with an aqueous scrubbing solution containing a reducing agent, scrubbing iodine into the solution, and circulating it until a predetermined iodide concentration is reached, exploiting evaporation to maintain high iodide concentration without excessive water addition.
Benefits of technology
This process effectively concentrates iodide in the scrubbing solution, allowing for efficient iodine recovery and recycling, reducing salinization, and enabling high-value reuse of iodine.
