LNG – sealing solutions for the liquefaction of natural gas

Natural gas is liquefied with compressors by cooling the gas to -163 °C (-261 °F). The volume is reduced by 600 percent. Then the liquefied gas is stored in containers and transported by ship or LNG tankers.

The special demands placed on the sealing systems for gas liquefaction include large shaft diameters up to 350 mm (13.78") in the compressors and enormous temperature differences up to 250 Kelvin (-110 °C ... +150 °C (-166 °F ... +302 °F)).

Gas-lubricated mechanical seals from EagleBurgmann have proved reliable under these conditions for over 10 years.
