METHOD AND APPARATUS FOR CAPTURING SOX IN A FLUE GAS PROCESSING SYSTEM |
摘要 |
Systems and processes for treating a flue gas for removing sulfur oxides (SOx) entrained in the flue gas generally includes contacting the gas stream with an aqueous alkali and/or alkaline earth metal hydroxide solution such as sodium hydroxide and reacting SOx entrained in the gas stream to form an aqueous alkali and/or alkaline earth metal sulfur-containing salt solution such as sodium sulfate. The aqueous alkali and/or alkaline earth metal sulfur-containing salt solution can be introduced into an electrodialysis apparatus configured to electrolyze water to form hydrogen and hydroxyl ions that selectively combine with alkali and/or alkaline earth metal ions and sulfur containing ions from the aqueous alkali and/or alkaline earth metal sulfur containing salt feedstream to form a regenerated alkali and/or alkaline earth metal hydroxide feedstream and an acid containing feedstream. |
