High-sulfur naphtha

[shvet]

Dear forummembers

Please advise

We have large amount of high-sulfur naphtha, let's say 2'000 ppmw S and 2'000 MT per month. Ar there end-users using such stock as a raw material? I do not know - solvent, vulcanazing agent, odorizing additive? I am interested in industry or process or similar, not in names of companies.

Sulfur (without the naptha) has a very large international market.

Unfortunately there is too much sulfer in raw naphtha and most all petroleum fuels and to get a better price for your naptha, you will probably need to extract it before marketing. Low sulfer petroleum is what everybody wants.

That is only some 600bpd at most. Setting up a HDT for 600bpd is simply not viable these days. Find a refinery you can sell it to. Info from Google says Arabian naphtha, which would be high sulfur, is selling at USD650/ton, so you'd probably get not more than USD600/ton at 2000ppmw sulfur?

Mixing with naphtha is not an option we would be satisfied at as it causes high discount. The idea is to find a customer who has no a reason to ask for a discount.

Sulfur extracted from naphtha has a large market in flakes for the chemical industry and is also used in the acidification of lands in North Africa. Naphtha with a high sulfur content poses problems during its processing, you can only get rid of it if the price is good to the buyer.

You find someone who is already processing similar material and sell it to them for whatever discount they ask for.
Unless you can remove the S this is as good as you will be able to do.

For low flow systems, mole sieves 13X and activated carbon adsorption of the polar sulfur compounds can be used for desulfurisation of heavy naphtha. Process is regenerable. See GPSA and also articles on the internet.
Another method is the licensed MEROX process

Thank you, gentlemen, but definitely that is not what I was asking for.

Naphta with high sulfer content is not a greatly desired comodity, but it is more valuable than dirt, if you can transport it economically to a refinery with Sour crude processing capability. Economic transportation may be the key question. That would appear to be the answer you are looking for.

Or maybe anybody that could get away with burning high sulfer gasolines for whatever use they might have.

Do you have a more specific question?
