LNG boil-off recycling

Natural gas is liquefied at temperatures of about –162°C at normal pressure. The unavoidable boil-off of gas from the liquid phase during LNG production, storage, and offloading is gathered and recycled for reliquefaction. Ultrasonic gas flow meters from SICK allow a precise and reliable fiscal metering of any boil-off losses inside a liquefaction plant even at cryogenic gas temperatures.
