Sulphur removal from syngas

[Andrea10]

Hi everybody!
I have to remove elemental sulphur from a 58 mol/h syngas stream (S 1.5% mol) at 900°C. Particularly, I need to get the elemental sulphur as I have to check if my catalyst is able to produce S from H2S (i.e. I can not use hydrogenation of S followed by amine absorption of H2S).
Does anybody have an idea about how I can do?
Thanks in advance.
Best regards

You have sulphur, but no H2S or COS? Try cooling it with steam first

Thanks bonzoboy for your reply!
Yes...H2S and COS are also present but in small quantities (1% mol more or less).
As this is a plant on bench scale there is no steam available...only hot and cold water.
What do you think about cooling the syngas stream first with hot water and then using a water scrubber (with the recylce of water and possible make up of NaOH in order to maintain the pH to proper values) with filters (in parallel) at the bottom in order to trap the sulphur?
Thanks in advance for your reply.
Bye
