Abstract
The present disclose is directed to a method for controlling iodine levels in wet scrubbers, and, in particular, recirculating wet scrubbers by removing the iodine from the scrubbing solution, such as by using ion exchange, absorption, adsorption, precipitation, filtration, solvent extraction, ion pair extraction, and an aqueous two-phase extraction.
Claims11
A system, comprising:
- an input to receive a waste gas comprising an acid gas and iodine;
- a wet scrubber to treat the waste gas to remove at least a portion of the acid gas and the iodine from the waste gas and form a scrubbing solution comprising at least one of an acid derived from the acid gas and a derivative thereof and iodine;
- and
- a carbonaceous material to remove, from the scrubbing solution, at least a portion of the iodine, thereby reducing a concentration of iodine in the scrubbing solution.
