The theoretical and experimental principles and design solutions for the technology for the extraction of hydrogen from gas mixtures formed during the decomposition of hydrogen sulfide using metal hydride technologies, allowing to obtain hydrogen of high purity and pressure, are considered. Analytical equations and dependences of the physicochemical properties of reversible metal hydrides and basic organic liquids that can be used as carriers are determined. It was determined that the enthalpy (ΔH) and entropy (ΔS) formation of metal hydrides are the most important parameters and their value determines the processes of absorption and desorption, as well as hysteresis. An experimental device has been created to study the processes of hydrogen extraction from the decomposition products of hydrogen sulfide and its compression at high pressures. A schematic diagram of a thermal sorption compressor device has been developed, which is suitable for use in industrial devices for compressing hydrogen obtained from the black sea hydrogen sulfide. The dependences of the mass fraction of hydrogen absorption in the separator sorber on the suspension temperature and its residence time in contact with the gas mixture at a pressure of 0.3 and 0.6 MPa are determined. The productivity of the process of extracting hydrogen from a gas mixture has been established. The dependences of the device productivity on the pressure of the mixture in the sorber and the pressure of hydrogen in the stripper and the temperature of the suspension are
The compact installation and technology for determining vibration characteristics by the ESPI method has been created. The experimental determination of the dynamic characteristics of a diamond circular blade with a diameter of 203.4 mm and a thickness of 1.19 mm using real-time electronic speckle interferometry is presented. 15 mode shapes of vibration were detected in the range from 100 to 5000 Hz. The program calculation of the natural frequencies and mode shapes is carried out for three values of the clamping inner diameter (42 mm, 44 mm, 46 mm). The options for calculating a disk with a rim and without a rim are considered. It is shown that the minimum mean squared error of the calculation is achieved for the values of the diameter of the disk 46 mm, 42 mm and 44 mm for the number of nodal circles 0, 1 and 2, respectively. To verify the accuracy of the interferometer, experimental, computational and analytical studies of console steel rod 200 × 22.25 × 3.78 mm in size were carried out.
