20.500.12556/RUL-140189 Analiza padca tlaka pri toku zmesi vodika in zemeljskega plina Analysis of pressure drop for hydrogen and natural gas mixture flow Shranjevanje in transport vodika, kot obetavnega nosilca obnovljivih virov energije, predstavlja hitro razvijajoče področje zelenega trajnostnega razvoja. V delu smo s pomočjo enačbe stanja GERG 2008 za čiste snovi in zmesi popisali termodinamične lastnosti vodika ter zmesi vodika in zemeljskega plina. V okviru analize padca tlaka pri toku čistega vodika ter pri toku zmesi zemeljskega plina in različnih molskih deležev vodika smo obravnavali vpliv temperature in tlaka fluida ter premera in dolžine cevovoda. Pri toku zmesi zemeljskega plina in vodika sta tlačni padec in hitrost zmesi v plinovodu močno odvisna od molskega deleža vodika v zmesi. Na osnovi pregleda literature smo zbrali smernice za zahtevano čistost vodika za vodikovode in za vtiskavanje vodika v plinovodna omrežje. Storage and transport of hydrogen, a promising carrier of renewable energy sources, represents a rapidly developing field of green sustainable development. In this work, GERG 2008 equation of state for pure substances and mixtures were used to describe the thermodynamic properties of hydrogen and mixtures of hydrogen and natural gas. As part of the analysis of the pressure drop in the flow of pure hydrogen and in the flow of a mixture of natural gas and different mole fractions of hydrogen, we considered the influence of the temperature and the pressure of the gas mixture, as well as the diameter and the length of the pipeline. In the flow of a mixture of natural gas and hydrogen, the pressure drop and the velocity of the mixture in the pipeline strongly depend on the mole fraction of hydrogen in the mixture. Based on a review of the literature, we compiled guidelines for the required purity of hydrogen for hydrogen pipelines and for injecting hydrogen into gas pipeline networks. enačba stanja GERG 2008 vodik zmes zemeljskega plina in vodika padec tlaka obnovljivi viri energije GERG 2008 equation of state Hydrogen Hydrogen/natural gas mixture Pressure drop Renewable energy sources true false false [G.
