Question

How much does it cost the desulfurisation process per barrel?

Answer 1

The answer depends on how dirty the oil is to begin with and how clean it has to end up. (The American diesel standard used to be 500 ppm, now 80% of it is supposed to be 15ppm:

The European standard was 350 ppm, then 50 ppm, and now is 15 ppm:

If you look at the end of this page:

the second reference, labeled  "Hydrodesulfurization Technologies and Costs", is a pdf file with some cost data.

Since this was announced in 2001, it probably isn't in production yet, but it suggests 2.5 cents/gal (not per barrel) is possible:
