Storing cryogenic liquids requires special equipment and measures to ensure the stability and safety of the liquid. Here are some of the key steps and points to store cryogenic liquids:
Choosing the right cryogenic container
The container should have sufficient capacity and a suitable structure to store the required cryogenic liquids.
The container should be made of a low-temperature, corrosion-resistant material, such as stainless steel.
The container should have good thermal insulation performance to reduce the impact of external heat on the liquid.
Keep the container tightly closed
Ensure that the cryocontainer is well sealed to reduce evaporation losses and contamination by external impurities.
Check whether the gaskets and seals of the container are intact, and replace the damaged parts in time.
Maintain a low temperature environment
Refrigeration systems or refrigerants such as liquid nitrogen and liquid oxygen are used to keep the inside of the container cold.
Regularly check the working status of the refrigeration system to ensure the normal operation of the system and troubleshoot in time.
Monitor temperature and pressure
Install temperature and pressure monitoring equipment to monitor temperature and pressure changes inside the vessel in real time.
Set up an alarm system to sound an alarm and take appropriate action when the temperature and pressure exceed the safe range.
Prevent Liquid Leakage
Set up a leak collection system, such as a leak tray or leak pit, around the container to collect leakage liquids that may occur.
Regularly inspect the vessel’s valves, pipes, and connections to ensure there are no leaks.
Pay attention to safety measures
In places where cryogenic liquids are stored and used, clear safety signs and warning signs should be set up.
Provide appropriate protective equipment such as protective eyewear, gloves, and protective clothing to ensure the safety of operators.
Operators are trained to ensure they understand the properties and operational requirements of cryogenic liquids.
Follow storage and transport regulations
Follow national and local regulations and standards for the storage and transportation of cryogenic liquids.
During transportation, appropriate protective measures should be taken to ensure the safety and stability of cryogenic liquids during transportation.
Recording and Management
Information such as storage time, temperature, and pressure of cryogenic liquids is recorded for traceability and management.
Regularly assess storage and shipping conditions to ensure they meet requirements and make adjustments as needed.
By following the above steps and points, cryogenic liquids can be stored efficiently and their stability and safety can be ensured.
