| Abstract: | Hundred million cubic meters of hydrogen should be stored and transported for the largescale hydrogen energy system. Liquid hydrogen storage has evident advantages among various storage methods in practical hydrogen system. Ten billion cubic meters of hydrogen are dissipated to the environment along with the emission of coke-oven gas every year in china. A new separation and liquefaction of hydrogen at the same time by means of a new cryogenic separation method was presented. The divisional liquefaction and segmented pressurizing model are proposal. The calculation indicated that segmented pressurizing can greatly decrease the energy consume. The calculation results provide a useful principle for the design of the large-scale hydrogen separation processes. |
