Ensure the safety and reliability of LNG storage tanks
Design pressure control system; Pressure control in the process of liquid feeding.
Design pressure control system: Establish a complete LNG tank pressure protection system, including overpressure protection, normal operation pressure regulation and negative pressure protection. For example, when the tank pressure reaches a certain threshold, the corresponding protection measures should be activated, such as leading the flare process to discharge overpressure gas or automatically open the pressure control valve to vent to the flare combustion and other ways to control the pressure.
Pressure control in the process of liquid feeding: In the process of liquid feeding, it must be ensured that there is sufficient nitrogen gas to replenish the jacket, and after the cryogenic liquid is filled into the inner tank, it should be ensured that the pressure of the jacket is within the permissible range, which is not more than 0.6MPa.
