Product Description High purity hydrogen liquefierProduct DescriptionThe hydrogen liquefaction system stands as a pivotal technological apparatus within high-tech industries such as large-scale scientific projects, aerospace, and new energy sectors. Serving as a critical manifestation of a nation's comprehensive competitiveness, this system plays a fundamental role in various aspects. Its application within the hydrogen utilization industry chain enables the efficient storage and transportation of liquid hydrogen at atmospheric pressure, presenting a remarkable breakthrough. This innovative capability significantly reduces transportation costs, bolsters application safety, and enhances the lifespan of hydrogen fuel cells, thereby addressing crucial challenges in the field. Moreover, the economic benefits and social value derived from the widespread adoption of the hydrogen liquefaction system are immense, creating opportunities for transformative advancements and sustainable development across industries and communities. Technological Process1. Hydrogen Compression: Gaseous hydrogen from the source is compressed using reciprocating or centrifugal compressors. The compression raises the pressure of the hydrogen gas, typically to several hundred bar, preparing it for further processing. 2. Hydrogen Purification: The compressed hydrogen gas undergoes purification to remove impurities that could interfere with the liquefaction process. Various purification techniques such as pressure swing adsorption (PSA), membrane separation, or catalytic processes are employed to remove moisture, carbon dioxide, and trace hydrocarbons. 3. Cooling and Pre-Cooling: The purified hydrogen gas is cooled using a heat exchanger and a refrigeration system. The gas is first pre-cooled using ambient air or cooling water to reduce its temperature. Subsequently, the gas is further cooled using a cryogenic fluid such as helium or nitrogen in a multi-stage heat exchanger to achieve a lower temperature range. 4. Liquefaction Cycle: The pre-cooled hydrogen gas enters the liquefaction cycle, which typically follows the Claude or Linde cycle. In this cycle, the gas is expanded through a series of expansion turbines, allowing it to undergo adiabatic cooling. The expanded gas is then condensed by counter-current heat exchange with a colder hydrogen stream, further reducing its temperature. 5. Condensation: The cooled and expanded hydrogen gas enters a series of condensers where it undergoes a phase change from gas to liquid. The gas is exposed to a colder hydrogen stream or a cryogenic fluid, causing it to condense and form liquid hydrogen droplets. 6. Separation and Storage: The liquid hydrogen is separated from any remaining gas and collected in cryogenic storage tanks. These tanks are designed to maintain extremely low temperatures, typically below -250°C (-418°F), to prevent evaporation and maintain the liquid state. Specialized insulation systems, such as vacuum insulation or multi-layered insulation, are employed to minimize heat transfer. 7. Distribution: The stored liquid hydrogen can be distributed via cryogenic tanker trucks or transferred to other storage facilities. Cryogenic transfer systems, including pumps and vaporizers, are utilized to maintain the low temperature and convert the liquid hydrogen back into gaseous form if necessary.5T/D1.5T/DProduct ParametersProduct modelWBH-1000Hydrogen liquefaction capacity1000 L/hHelium mass flow rate428 g/sLiquid nitrogen consumption840 L/hCompressor electrical power550 KW x 2Operating pressure4-20 barHydrogen purity>6 NContinuous operation>8000 hTurbine speed81700 r/minSpecific power consumption0.866 KWh/L, 12.81 KW/kg Product modelWBH-1500Hydrogen liquefaction capacity200-2500 Kg/DOperating pressure4-20 barHydrogen purity>6 NContinuous operation>8000 hTurbine speed81700 r/minSecondary hydrogen content≥95% Product modelWBH-5000Hydrogen liquefaction capacity5-100T/DHydrogen purity≥99.999%Secondary hydrogen content≥95%Plant size5-30 T Hydrogen Liquefaction Unit Product AdvantagesUtilizing Helium Refrigeration in Hydrogen Liquefaction Cycle: By not using hydrogen as the working fluid in the cycle, this approach ensures safety and offers easy regulation of liquefaction capacity.
