The primary causes of the rise in cryogenic storage tank liquid losses
Liquid nitrogen storage tank self-pressurization impact
Liquid nitrogen storage tank self-pressurization impact: the supercharger valve is not closed tightly or internal leakage, the leakage of liquid through the supercharger vaporization, so that the pressure of the equipment continues to rise, when more than the set pressure of the tank began to empty through the automatic venting valve, the equipment in order to maintain their own pressure stability, the liquid will continue to pass through the supercharger, and vaporized after the release of the air, which will inevitably increase the loss of liquid in the storage tank. In addition, there will be valve body frost, the valve body temperature will be lower than other parts of the temperature.
