Installation for storing pressurized liquefied gas and security device therewith

摘要

The gas storage tank (30) is pressurized to contain the liquefied gas. The container has a wall thickness calculated using parameters of pressure and temperature. The circuit has sensors (20) to define the value (G) of the effective temperature of the container wall, and a memory for the value of the calculated temperature. The two values are compared (42) and valves (38,40) reduce the pressure to a value inferior to the calculated pressure resulting from a comparison of the calculated and sensed temperatures. Claims include a method of storing the gas
