The operational and protective procedures for the use of low-temperature liquid nitrogen storage tanks should include the following:
Staff Training: All operators must undergo safety training for liquid nitrogen storage tanks, understanding the properties, hazards, and proper operating procedures as well as emergency response measures.
Protective Gear: Operators must wear appropriate protective gear, including gloves, protective suits, and non-slip shoes, to safeguard themselves from the low temperatures of liquid nitrogen and other hazards.
Ventilation Requirements: Adequate ventilation must be maintained within the operational area of the liquid nitrogen storage tank to expel gases produced by the evaporation of liquid nitrogen. Avoid excessive oxygen concentrations to minimize the risk of fire and explosion.
Leak Control: Tanks must be equipped with leak detection and alarm systems to promptly identify and control the leakage of liquid nitrogen. In the event of a leak, immediate measures should be taken to control the source of the leak and to carry out repairs.
Fire Prevention Measures: Nitrogen liquid has a low boiling and freezing point, which is prone to fire. Measures such as setting up firewalls around nitrogen liquid storage tanks and using fire-resistant coatings are taken to prevent fires from occurring and spreading.
Electrostatic Protection: The accumulation of static electricity in liquid nitrogen tanks can cause sparks, increasing the risk of fire. Measures such as using electrostatic conductive materials and anti-static equipment should be taken to reduce the accumulation and release of static electricity.
Regular Inspections and Maintenance: Conduct regular checks on the condition of liquid nitrogen tanks and related equipment, including valves, pipes, pressure gauges, etc. Ensure the equipment is in perfect condition, and promptly repair or replace any damaged parts.
Waste Gas Treatment: Liquid nitrogen tanks produce waste gas during operation, and appropriate waste gas treatment measures must be taken to prevent harm to the environment and human health.
Emergency Response Plan: Develop an emergency response plan for liquid nitrogen storage tanks, including procedures for handling leakage accidents, emergency rescue measures, and protocols for notifying relevant departments. Operators

Low-temperature industrial gas filling stations are equipment used to fill liquid low-temperature industrial gases (such as liquid oxygen, liquid nitrogen, liquid argon, etc.) into gas storage tanks. Here are some basic facts about low-temperature industrial gas filling stations:
Tank Type: Low-temperature industrial gas tanks typically employ double-walled vacuum insulated tanks, where the inner wall is used for storing liquid gas and the outer wall for insulation to minimize heat transfer and evaporation losses of the liquid gas.
Filling Equipment: Low-temperature industrial gas storage tank filling stations include liquid-gas filling pumps, filling pipelines, flowmeters, pressure sensors, and other equipment. The liquid-gas filling pumps are used to extract liquid gases from storage tanks or gas cylinders and fill them into the target storage tanks.
Filling Process: The operational procedure at the filling station typically includes the following steps: Preparations (checking equipment, preparing filling medium), Equipment Connection (connecting filling pumps, pipelines, etc.), Equipment Activation (starting the filling pump, adjusting flow and pressure), Filling Operation (filling liquid gas into the target storage tank), Monitoring and Control (monitoring parameters such as pressure and flow during the filling process to ensure safety and quality), and Completion of Operation (shutting down equipment, cleaning the work area).
Safety Measures: Strict adherence to relevant safety operating procedures and standards is required during the operation of low-temperature industrial gas storage tank filling stations. Operators should receive training to understand the properties and safety precautions of liquefied gases. Additionally, filling stations should be equipped with safety equipment such as pressure sensors and safety valves to ensure safety during the filling process.
Quality Control: Quality control is essential during the filling process at the filling station, including monitoring parameters such as flow rate, pressure, and temperature of the filling medium to ensure accuracy and quality of the filling.
It's important to note that the operation of low-temperature industrial gas storage tank filling stations must be conducted by trained personnel and strictly adhere to the relevant operational procedures and safety measures. Additionally, the design and manufacture of the filling stations should comply with applicable standards and regulations to ensure the safety and reliability of the equipment.
