The storage duration of oxygen depends on several factors, including the storage method, container type, and environmental conditions. Oxygen is commonly stored in compressed gas cylinders or as liquid oxygen. Here's a breakdown of the storage durations for each type:

Liquid oxygen

Liquid oxygen is stored and transported at very low temperatures, typically around -183 degrees Celsius (-297 degrees Fahrenheit). This extreme cold keeps oxygen in a liquid state, allowing for more efficient storage compared to compressed gas cylinders. The storage duration of liquid oxygen depends on factors such as:

• Storage Capacity: The amount of liquid oxygen stored determines how long it will last before needing replenishment.

• Evaporation Rate: Liquid oxygen slowly evaporates over time, especially when exposed to ambient temperatures. The rate of evaporation influences storage duration.

• Insulation: Proper insulation of liquid oxygen storage tanks helps maintain low temperatures and reduce evaporation, extending storage duration.

Liquid oxygen can be stored for several weeks to months, depending on the size of the storage tank, insulation quality, and usage rate.
