The safe and stable operation of liquefied natural gas (LNG) storage tanks is crucial for energy supply. To ensure the safety of the storage tank and prevent over-temperature and over-pressure phenomena, it is necessary to strictly control the operating parameters. Over-temperature and over-pressure may be caused by operational errors or overfilling. The specific reasons and countermeasures are as follows:
I. Key Points for Safe Operation
Avoid operational errors
Set up identification plates on key devices (such as valves), clearly indicating the opening and closing direction, status and precautions to reduce human errors.
Operators must undergo professional training, be familiar with the process, and ensure that each step complies with the standards.
Prevent overfilling
Fill strictly in accordance with the designed capacity. If overfilled, immediately drain the excess liquid.
Regularly calibrate the filling instruments to ensure accuracy; The liquid level gauge needs to be cleaned regularly to avoid reading errors.
Count the weight of the residual liquid to avoid overloading due to neglect. In high-temperature environments, the temperature is reduced through a spray system to prevent pressure from rising.
Ii. Maintenance and Care Specifications
Environmental and storage requirements
Storage tanks should be placed in well-ventilated areas, away from fire sources and heat sources (with a distance of no less than 1.5 meters), and are strictly prohibited from being exposed to direct sunlight or roasted by fire.
Regularly check the airtightness of valves and pipeline joints. Use soapy water to detect leaks. Open flame leak testing is strictly prohibited.
Daily maintenance measures
Establish a regular inspection system, record parameters such as pressure and temperature, and deal with any abnormalities in a timely manner.
Clean the surface of the tank to prevent corrosion. Check the safety valve, pressure gauge and other accessories to ensure they are functioning properly.
When not in use for a long time, drain the internal medium, cut off the power supply, and take proper moisture-proof and rust-proof measures.
Iii. Summary
The safety of LNG storage tanks can be significantly enhanced through standardized operation and regular maintenance. Operators must strictly abide by the guidelines. Enterprises should enhance training and supervision to ensure the stable operation of equipment and reduce the risk of accidents.
