The function of the gas-liquid equilibrium valve in the LNG unloading area
Thread Content
Could a friend please explain the function of the gas-liquid equilibrium valve in the LNG unloading area? Thank you
The purpose of the balance valve is to prevent the liquefied LNG in the tank from vaporizing and causing pressure to rise, which could lead to excessively high pressure in the liquid-phase pipelines.
After LNG is unloaded, some LNG remains in the liquid-phase pipeline; as it vaporizes, the pressure in the pipeline increases. To prevent pressure buildup, a gas-liquid equilibrium valve is used to regulate the pressure
