Fullcryo Small And Medium Hydrogen Liquefaction Unit
Product Description
A hydrogen liquefier is a device that converts gaseous hydrogen into liquid hydrogen through a series of cooling and compression steps. Liquid hydrogen has a higher energy density and is easier to store and transport compared to its gaseous form. Here are some key aspects of hydrogen liquefiers:
Basic Principles
The primary principle behind hydrogen liquefiers is to cool gaseous hydrogen to its liquefaction temperature (approximately 20.28 K or -252.87°C). Common liquefaction methods include:
◆Claude Cycle: Utilizes the expansion and cooling effect of hydrogen gas through multi-stage compression and expansion.
◆Joule-Thomson (JT) Effect: Achieves cooling and liquefaction through the adiabatic expansion of hydrogen gas.
◆Brayton Cycle: Uses helium or hydrogen as a refrigerant to cool and liquefy hydrogen through a reverse Brayton cycle.This is exactly the principle of Fullcryo’s hydrogen liquefaction unit.
Key Components
1. Compressors: Used to compress hydrogen gas to a high-pressure state.
2. Heat Exchangers: Facilitate heat transfer between different temperature levels, gradually lowering the temperature of hydrogen gas.
3. Expanders: Provide cooling effect through gas expansion.
4. Cold Box: Contains the above components and provides an insulated environment to minimize heat loss.
5. Liquid Hydrogen Storage Tanks: Used to store the liquefied hydrogen.
