Economic dealing with H2S separated from Amine Unit

Economic dealing with H2S separated from Amine Unit

Economic dealing with H2S separated from Amine Unit

Any one has former experience to advice;
Which will be more economic, converting H2S to elemental sulfur or to Sulfuric acid?

RE: Economic dealing with H2S separated from Amine Unit

Do you have access to an acid plant?
What is the relative value in your local of S and H2SO4?
What is the required energy input for the two options?

RE: Economic dealing with H2S separated from Amine Unit

Dear EdStainless,
Thank you for your response,
I have not access to an acid plant.
S price = H2SO4 price * 2.59
I do not energy inputs.

If available, what is the relative capex & Opex of SRU to Sulfuric acid plant in the case of the same H2S feed to both plants?
For the current case , Acid Gas Stream as following:

I would start by contacting the companies that build this equipment. There are a handful world wide that design and build acid plants, likewise there are ones building pure S facilities.
