Karazin popup.description2 Subject of investigations - processes of extraction of hydrogen sulphide from sea water. The purpose of investigations - theoretically and experimentally to research the ways of the energetic favourable uprise of hydrogen sulphide water on necessary technological height and methods and technologies of extraction of hydrogen sulphide from sea water. The methods of investigations - theoretical analysis, modelling and physical experiment. According with the contract the following results have been obtained. The lifting technology of the uprise of hydrogen-sulphide water on a technological height above sea level for maintenance of extraction of hydrogen sulphide from sea water and reception of added energy is offered due to use of the energies: of a hydrostatic pressure , of a temperature and salt gradients, of the winds and waves, of a hydrogen sulphide. The model of technological installation for model operation of lifting technology gas saturated ocean water from deep-seated layers of Black sea with the help of lifting technology designed. The model is capable experimentally to show the fluids lifting and to explore dependence this lifting from different parameters: gas saturation, salt content, temperature of a fluid. It is offered uses of a principle of scale similarity at model operation lifting of hydro sulphuric Black Sea water. The test stand for imitation of the conditions of extracting of hydrogen sulphide has been adjusted. The test stand includes a model of installation and peripheral devices for lifting maintenance which is simulated at different conditions: a different gang of fluids; different equals of gas saturation; different temperatures and pressures in a balloon; that simulates sea water from the outside tubes; different tubes with wettable or not-wettable interior surfaces. For the first time the exhaust of gas blisters from a fluid which is far from full saturation is explored. The constitutive equation of gas bubbles dynamic in fluid is obtained, conditions of existence and parameters of stationary bubbles in fluid, and also the dynamics of gas bubbles in a fluid at diminution of external pressure are described. The experimental research of effects of a depressurizing speed on origination of bubbles of gas for model operation of extraction of gas saturated water from the given depths are carried out. It is shown, that at high speed uprise of hydrogen-sulphide water from depths of 1000 m on a sea surface the gas will be depressurize during 1 sec approximately. It has been proved at experiments on the water, under such parameters the single gas bubbles will increase in volume and to provide to origination of gas-lifting effect. The experimental research of this technology with the purpose of definition of optimal modes of functioning of a model of technological installation have shown, that the water lift height in an intake pipe of model devices is increased by giving an interior surface of a pipe of quality of wetting. Thus the increase of water salinity (at depth of water takeoff) give increase of height of its uprise in an intake pipe, and, thus, to increase of technological height which will allow to increase an overall performance the hydrosulphuric power generated complex.
