The results from the laboratory-scale extraction pilot plant unit for the separation of H(2)S from Black Sea water lead us to build a novel industrial extraction pilot plant to concentrate H(2)S from 10 ppm. to above 10000 ppm. The processing of 10(9) m(3) of water containing 10 ppm will produce 0.833 tons of hydrogen and therefore a technology for extraction and concentration of H(2)S is essential. The conceptual pilot plant proposed in this paper is in principle similar to the laboratory pilot plant developed in the University of Duhok, Iraq, and it could work to pump water directly from Black Sea. It contains a screen with electrical heater to fix the temperature of stripping, a water chiller at the top to separate any water droplet or vapor. The research on industrial pilot plant has shown that, this unit could operate both on and underneath the surface of the sea.
