To popularize the operating standards for LNG liquid vacuum storage tanks
Anti-tank conditions and standards for LNG storage tanks
1. Feasibility analysis of fuel tank pouring
When a leakage accident occurs during the use of the water tank, analyze the leaking tank to confirm whether it is possible to fill the water tank.
1) In case of partial loss of vacuum, a small amount of leakage or liquid leakage of the tank, the tank should be inverted.
2) When a large amount of leakage occurs due to the loss of tank vacuum, root flap failure, etc., and a certain amount of effusion and vapor cloud are generated, the inversion treatment is not considered. When a leakage accident occurs in the mobile LNG container during transportation, analyze the fuel tank And the accident situation of the driving mechanism, confirm whether it is possible to fill the fuel tank.
3) When the running mechanism is still working, the tank is slightly damaged, the leakage is small, or the leakage is controlled.
4) The driving mechanism is out of order and the tank is slightly damaged. Supervise the scene to prevent the entry of irrelevant personnel. Make preparations for firefighting and extinguishing.
5) A large amount of leakage occurs due to the loss of the tank body vacuum or the fracture of the root valve, and the filling of the tank is not considered.
2. Working conditions for pouring into the container
1) Delimit the hazardous area according to the standard of the LNG container type that is poured into the necessary tanks, establish obvious signs and safety cordon, prohibit irrelevant personnel from entering the scene, configure dry fire extinguishers, mobile high-expansion foam fire extinguishing systems or fire trucks to clean up combustibles The high-rate foam covers the surface of the LNG and is isolated from the air. When the leaked LNG has caught fire, use a dry fire extinguisher. The fire extinguishing agent is potassium carbonate. Extinguish the fire, and after evaluating the feasibility of the implementation of the tank dumping, the tank dumping operation shall be carried out.
2) Ensure that the filling tank is well ventilated at the work site, and if necessary, take forced ventilation measures to increase air flow. At the same time, ensure the on-site rescue communication and external communication network for the filling.
3) Dumping tank operators must receive professional training in the operation of LNG containers. All falling operators must not carry communication equipment, lighters and other fires, wear a full set of protective equipment, use antifreeze gloves, and eliminate static electricity before entering the site.
4) Investigate the changes in the composition and density of the LNG liquid at the site, ensure the same oilfield liquid as the receiving container (except for the case where the receiving container is empty), and propose implementation plans for fire extinguishing, tank filling, and blockage.
