Nitrogen LiquefierWorking Principle
The cryogenic mixed refrigerant throttle refrigeration system is employed in this nitrogen liquefier. This system leverages a regenerative multi-component mixed refrigerant throttle refrigeration cycle. It uses high, mid, and low boiling point pure components to create multi-component mixed refrigerants. The effective refrigeration temperature zones of each boiling point component relay match perfectly, facilitating cooling from ambient temperature down to -196°C,thus achieving nitrogen liquefaction (-180°C @ 0.6 MPa) seamlessly.
