If I want to safely bind chlorine gas for disposal. I am to understand activated carbon will do. I also have heard something about using steal wool. Is one better then the other?

I thought a caustic scrubber was typical?

I use a sodium hydroxide solution, but I guess steel wool will work if at a high enough temperature. I've use steel wool and chlorine to make iron (III) chloride, but I doubt the absorption was complete.

I think the causitc scrubber idea sounds better. I can use Sodium Hydroxide? Or is Sodium Carb or Bicarb better? Is there any designs out that that can maximize the contact time with the solution? Perhaps I could use a PH indicator to tell me when the scrubbing solution is expended? Or should I do it through a dry packed column like co2 scrubbers?

Thank You

We dispose Cl2 (that is otherwise utilised in HCl synthesis & NaOCl synthesis) by channeling it to a scrubber (a vertical ~100m concrete structure which is at a suction of ~200mmH2O via blower). Scrubbing agent is hydrated CaO slurry which is circulated via pumps, it turns pink (CaOCl) & we just visually get the idea of when it's exhausted

100m tall? Or was that a typo?

No is not... we produce tons of Cl2 via membrane electrolysis. In case of any emergency that had to be purged somewhere & disposed of safely

Very interesting. I've only seen flue stacks & distillation columns that high.

Could you post a pic? I'd love to see this. A 100 m tall concrete scrubber ain't something one gets to see every day!
