LNG composition measurement in tank run-down

LNG composition measurement in tank run-down

Optimize your LNG liquefaction process and improve storage safety

During tank run-down, LNG quality is measured before transferring to storage tanks to ensure it meets specifications. This step also boosts LNG storage safety by preventing fill-induced tank roll over and auto-stratification effects. Some measurement technologies can be problematic. GCs/vaporizers have slow results and higher OPEX due to vaporization, sample conditioning, and vaporized gas transport costs. They are also sensitive to LNG flow rate changes, causing inaccurate readings.

  • Delay-free LNG composition measurement

    with no consumables or sample conditioning

    Endress+Hauser Raman analyzer solutions offer real-time LNG composition measurement for better feedback control of the liquefaction process. Accurate and reliable analysis enables process optimization and composition adjustment to ensure LNG sent to storage tanks meets specifications. By helping to prevent roll-over, our Raman technology also increases storage safety. In addition, our analyzers do not require sample transport or vaporization for measurement which speeds results and lowers OPEX.
