Major Functions Unloading Gasify LNG in the tanker by vaporizer and return to gas phase of tanker to raise pressure in the tanker,and download LNG into cryogenic storage tank by differential pressure through top filling port.
Pressure regulation of storage tank When tank pressure is excesssively high, use BOG in the tank preferentially; when pressure is low, pressurize regulating valve is opened automatically, LNG flow into booster and gasified through liquid phase pipeline, after that return to the tank to nse pressure.
Gasification LNG in storage tank flow into vaporizer through outlet port, after gasified by vaporizer, temperature up to one that not less than ambient tenlperature 5-15 t . Heat exchanger is necessary, where low winter temperature present.
Pressure regulating Regulate gasified natural gas by regulating device to supply to user with suitable pressure and able to enter pipe network.
Metering If need to measure flow of natural gas, flow meter needs to be equipped after regulating.
Odorization Odorizing before natural gas into pipe network by manual or automation, ensure gas leakage can be detected.
Venting When pressure is higher than MAWP, open safety valve automatically, gas is vented to air through EAG heat exchanger.
