Nitrogen LiquefierWorking principle
The cryogenic mixed refrigerant throttle refrigerator employed in this nitrogen liquefier is based on the regenerative multi-component mixed refrigerant throttle refrigeration cycle. It incorporates high, middle, and low boiling point pure components to create a multi-component mixed refrigerant. By effectively matching the refrigeration temperature zones of each boiling point component, it achieves cooling from ambient temperature down to -196°C.The nitrogen liquefaction purpose (-180°C @ 0.6 MPa) is accomplished.
