  1. 785. C2Po1H-01 [43]: Thermodynamic and economic aspects of the Nelium Turbo-Brayton refrigerator development for the FCC-hh
    Steffen Kloeppel (TU Dresden)

    Poster Presentation

    Within the conceptual design study for the Future Circular Hadron Collider (FCC-hh) it was shown, that a large part of the total cryogenic heat load falls into the 40 to 60 K temperature level. Thus, additional cryogenic refrigerators for this temperature level are specified for each of the 10 foreseen cryoplants. Such cryogenic system was developed at the TU Dresden and is based on a Brayton...

  2. 631. C2Po1H-02 [44]: Dynamic simulation of a medium-sized hydrogen liquefier based on EcosimPro simulation software
    Dr Jing Li (the Technical Institute of Physics and Chemistry)
    23/07/2019, 09:00
    Poster Presentation

    A dynamic simulation of a medium-sized hydrogen liquefier has been proposed using process simulation software EcosimPro. A helium refrigerator with one turbine provides cooling power for this hydrogen liquefier. A dynamic simulation model based on Ecosimpro has been established according to the designed process flow. The pressure ratio of the helium compressor is 2/16 bar. The helium mass flow...

  3. 733. C2Po1H-03 [45]: Process analysis and optimization of 1000L/h medium-scale hydrogen liquefaction cycle
    Yonglin Ju (Shanghai Jiao Tong University)
    23/07/2019, 09:00
    Poster Presentation

    With the rapid development of world economics and increasing environmental problems caused by the harmful gaseous emissions, the low or zero emissions and frequently reused resources, renewable energies are regarded as sustainable replacements to fossil fuels. Hydrogen, as a kind of clean and efficient energy, would play a key role in future energy systems of the world and possible to become...

    Poster Presentation

    The commissioning of China Spallation Neutron Source(CSNS) cryogenic system was completed on July, 2017. It run 258 days totally until July, 2018, and the time of the longest continuous running is 184 days. CSNS passed national accept on August, 2018. Now it is running steady from September 19th. There is no any fault in the process of running. However, cryogenic system need to be improved in...

  5. 904. C2Po1H-06 [48]: Thermodynamic Design of Hydrogen Liquefaction Systems to Utilize LNG Cold Energy
    Ho-Myung Chang (Hong Ik University)
    23/07/2019, 09:00
    Poster Presentation

    A thermodynamic study is carried out for the design of hydrogen liquefaction systems with pre-cooling to utilize the cold energy of Liquefied Natural Gas (LNG). As liquid nitrogen is commonly used as pre-cooler of hydrogen liquefaction, LNG is proposed as an alternative, since the need of liquid hydrogen and the import of LNG are simultaneously increasing in Korea. Two different liquefaction...
