Looking for accepted method of checking activated charcoal filtering of H2S.?

Question

The company that manufactuers the device states the best method of checking is by weight however the filter weights approximately 680Kg, they give a limit of 4.75Kg from labeled weight. There should be a more accurate method without exposing the filter to gaseous H2S. Any suggestions are welcome.

Answer 1

I am not sure that there is a good answer to your question that you can apply but possibilities occur to me:

1 Keep track of feedrates and its H2S concentration and calculate the H2S the bed is exposed to allowing a safety margin.

2 If there was a probe inserted into the bed say 80% of the way through the bed and check H2S concentrations at that point.

3 Install a smaller back up filter downstream and test for H2S breakthrough between the filters. Replace both filters when this is detected.

Answer 2

Just a safety note your charcoal will not take all the H2S out if the concentration is too high, The old gas mask used that technique and many people died ,
Good luck
