Is the deodorization tank located next to the top of the acidic water tank generally made of Fe2O3, ZnO, or something else?

I have two questions: 1. How can it be ensured that the H2S vaporized from the top of the acidic water tank at such low pressure can be absorbed? 2. Does the deodorization tank need to have one in use and one as a backup? O(∩_∩)O Thank you
Iron oxide is prone to spontaneous combustion, so it is used less these days
There’s no need to worry about iron oxide; ferrous sulfide can catch fire on its own, and this isn’t a joke. Even pure zinc oxide can suffer from problems such as caking, which leads to an increase in resistance. It is recommended to use liquid alkaline deodorants, which can be fed into the stripping tower once they have reached saturation. For pressure balance issues, self-priming vacuum pumps or small pumping devices similar to water pumps can generally be used.
