The difficulties of the extraction of hydrogen sulfide from the Black Sea water and methods to overcome them

Among the alternative energy sources, of particular importance is the hydrogen energy industry, whose advantage over petroleumil products consists in its high environmental safety and caloric content, inexhaustible natural reserves, its use in the internal combustion engines, and so on. Among the hydrogen-containing raw materials used in the fuel elements, particular attention is paid to hydrogen sulfide, which is disintegrated into sulfur and hydrogen. One of the biggest sources of hydrogen sulfide is the Black Sea, whose total volume is increasing annually by 4–9 million tons. The paper dwells on several methods for extracting hydrogen sulfide from the Black Sea basin, as well as associated difficulties. It also presents methods for the decomposition of hydrogen sulfide, of which special mention should be made on the plasma–chemical membrane technology.This work was supported by Shota Rustaveli Georgian National Science Foundation (SRNSF) [DP 2016_5.
