Observation of pressure gauge and liquid level gauge during the filling process of lng storage tank

Gas phase pressure in lng storage tank

LNG is usually stored in cryogenic storage tanks at -162°C and a pressure of about 0.1MPa.

Content

(3) During the observation of the filling process, try to maintain a pressure difference of 0.2 MPa on the pressure gauge and liquid level gauge. (If the pressure rises above the filling and delivery pressure or approaches the relief valve pressure, the gas discharge valve must be opened to properly discharge the gas phase in the tank).
