Role of Sulfur to Acquire Hydrogen from the Black Sea

Research in areas of about 200 m in depth has proved that there is a quite intense amount of H2S. Even at the depths of 30–40 m, the presence of the gas has been detected. It is possible to obtain hydrogen and sulfur from H2S by using a converter or by means of other methods. Sulfur is a very valuable gas in economic terms. Quantity of sulfur-containing resources decreases day by day in our country. The Black Sea is rich in hydrogen and sulfur. The aim of this work is to develop new methods for acquiring hydrogen and sulfur from H2S, which is handled as energy source and raw material.

Flutter of a Membrane in a Stagnation Flow

The membrane is located at the stagnation point of the flow and is of finite width but infinite length. A rigid wall extends through the finite width of the membrane to infinity. The flow is considered to be a small perturbation on the two dimensional potential stagnation flow solution due to the vibrations of the membrane, and the membrane is modeled by the linear vibration equation. The resulting coupled problem is solved by a Galerkin procedure and the eigenvalue equation relating the membrane frequency to the other parameters is derived.

This test is suggested to use in determination of the facing properties of the resistant materials (Kuenzi, 1951). This study was carried out to perform bending test of sandwich constructions suitable for ASTM D7249/D7249M standards and to determine facing material properties of sandwich constructions through evaluating the experimental data. Performing and conducting of the test: this study was carried out with collaboration of the Istanbul University and Turkish Airlines Technic under privacy in order to determine the facing properties of the sandwich constructions and it includes experimental and numerical methods. The study was carried out based on accepted standards.

It will be different from an ordinary oil platform as it will generate energy from hydrogen sulfide instead. The construction of this platform is foreseen as a Green Project. While the platform is cultivating energy out of hydrogen sulfide, it will also be purposed to contribute to the ecosystem at the same time. Once it completes its function, the platform is planned to be fully recycled and recovered.

The suboxic zone of Black Sea is about 50 m thick and lies between the oxygenated surface layer and the anoxic depth at about 200 m. Hydrogen-sulfide layer appears in the Black Sea, mainly because it is highly isolated from the open ocean, when oxygen consumption due to the input of decomposable organic matter sinking from the upper euphotic zone or added by rivers flowing into the sea exceeds the oxygen supply to deep waters. Hydrogen-sulphide in the Black Sea, whose source is the process of anaerobic decomposition of organic matter of sulfate-reducing bacteria, is one of the world's most poisonous and is a possible energy source today. If the equilibrium in this very special sea is not maintained and steps towards healing is not taken, environmental disaster is likely to happen. The initial signs wil...

The possibilities for hydrogen production from H<sub align=right>2S and storage in the Black Sea

International Journal of Nuclear Hydrogen Production and Applications, 2009

Since the hydrogen sulphide zone was discovered in early 19th century in the Black Sea, it has been adopted that there is no life in the depths of the Black Sea and there are only bacteria live in the hydrogen sulphide layer. High content of organic matter, with maximum processes of bacterial sulfate reduction is the major source of this hydrogen sulphide zone. Hydrogen sulphide is one of the most poisonous gases in the world but it has great economic value to obtain hydrogen via dissociated into hydrogen and sulphure. Thus the Black Sea is not only has a serious environmental contamination but also has potential source of hydrogen energy, if a decomposition process can be developed. In this study, the sources of hydrogen sulphide, environmental impact of hydrogen sulphide in the Black Sea, the available techniques of hydrogen production from hydrogen sulphide and the possibilities of hydrogen storage by the natural sources in the Black Sea have been investigated.
