H2S removal from air
H2S removal from air
(OP)
What are the options to remove H2S from air?
I'm talking about H2S generated at wastewater plants and dispersed in the air or at sewage pumping stations.
May we use a pulverization of amine solutions in the air?

Good luck.

There is a little problem to use these alternatives.
We cannot confine the odor source to use a biofilter or srcubber.
These odor sources are dispersed around the site and each one needs an odor control.
Other place with H2S is the sewagwe pumping stations located inside houses neighbourhood.

In what condition would it be decomposed (pressure, temperature)? How long would it be decomposed and to what extent is the decomposition (ie.certain concentration of thiolgycolic acid and/or imidiazoline thioglycolate will produce how much h2s)?
please be kind to reply the answer at piglet275@lycos.com
Thank you very much.

This location may have biological, chemical or catalytic chemical scrubbers, carbon filters, activated alumina beds,or ozone contactors.
Alternatively, it is possible to dissolve the H2S by increasing the pH, or inhibit H2S production using nitrate or other proprietary chemicals.
There are any numbers of firms here in the UK offering such services. I assume the US is no different.

Bt the way, don't forget how expensive scrubbers and biofilters are, and the electricity for these large blowers must be considered when looking at total cost of ownership.

Often when you remove the H2S you will find other low odour concentration compounds that produce an offensive smell, so you might need to consider polishing technologies such as Biofilters or Activated carbon to remove these components (such as dimethyl sulphide, dimethyl disulphide and other VOCs).
Dosing the sewer is probably more effective as a corrosion control & asset management tool, rather than odour control. You need to be careful of not affecting sewerage quality & you are also assuming all the odour is H2S.
As mentioned above if the odour is complex sulphide, nitrogen or VOC based then dosing may not be the whole solution.
Hope this helps

There are alternative low cost / non hazardous solutions to your problem and specifically to “open space” odor control.
