What components are typically part of a liquid oxygen storage and supply system?

• A. A simple plastic bag
• B. Cryogenic storage tank with inner and outer shell, a vaporizer, a pressure control system, and piping
• C. A basic aerosol can
• D. A standard gas cylinder without valves

Answer: (B)

Liquid oxygen is stored as a cryogenic liquid, so a proper storage and supply system uses an insulated cryogenic tank with an inner vessel inside an outer shell. It includes a vaporizer to convert the liquid to gas for use, a pressure control system to regulate delivery and prevent overpressure, and piping to move the LOX to points of use. Boil-off gas is vented safely as part of the design. A simple plastic bag cannot contain cryogenic liquid and would fail at such low temperatures. A basic aerosol can isn’t designed for liquid oxygen or cryogenic operation. A standard gas cylinder without valves isn’t suitable for storing or regulating liquid oxygen and lacks the necessary insulation, vaporizer, and pressure control.
