H2S removal from CO2 Acid Gas Stream

H2S removal from CO2 Acid Gas Stream

H2S removal from CO2 Acid Gas Stream

(OP)
Small gas operator in Canada looking for metheods to selectively remove H2S from CO2 acid gas stream , coming from Amine sweetening .

RE: H2S removal from CO2 Acid Gas Stream

Look up Klaus Process.  Basically you send the stream to a combuster and convert the H2S into elemental sulfur, fire, and water--all the ancient "elements".

RE: H2S removal from CO2 Acid Gas Stream

I thought so too, till I recently wrote a paper for the API and a guy from Exxon said I spelled it wrong.  I searched and found 6 technical references that spelled it Klaus, and 2 that spelled it Claus.  It concerned me that one of the two was Wikipedia.  Either spelling will return a bunch of results.

I only knew it from the Shell SCOT process - Shell Claus Offgas Treating.

RE: H2S removal from CO2 Acid Gas Stream

There are quite a few options for this.  You could look at the old iron sponge process, liquid phase direct oxidation process, sulfa-treat, triazine, formaldehyde, crystasulf.....the list goes on.  

What's the composition of the acid gas stream and why are you removing the H2S?  Are you venting the CO2 or using it for EOR?

RE: H2S removal from CO2 Acid Gas Stream

(OP)
First of all, thanks to you all for resonding to my post. We are aware of Klaus, sulfa-treat, etc, but we have developed technology to deal with h2s and our main concern is finding a method/chemical to absorb h2s and slip the CO2.

Thanks for any further info on this.

RE: H2S removal from CO2 Acid Gas Stream

All the processes I listed will do exactly that - selective absorption of H2S from a gas stream.  No CO2 pickup.
