Storage Systems for Cryogenic Liquids

In designing a storage vessel for a cryogenic liquid, there are several considerations that should be made Is the system intended for long- or shortterm usage What type of liquid will be stored, and what rate of liquid loss can be tolerated Will the system be mobile or stationary What acceleration effects are anticipated for the system How much time and cost will be allowed for cooldown What will be the stratification and pressure effects on the system What type and thickness of material will be required for the inner and outer vessels and what will be the thermal conductivity of this material Other important aspects include the optimum type of insulation and the design of inner vessel supports, fill and drain lines, vapor vents, vapor diffusers, antislosh baffles, and safety devices. 

Low density Easily damaged during handling with 

Readily available Flows with difficulty when crushed 

Not toxic Cannot be used to insulate moving parts 

Recoverable even after water contact Needs protection from atmosphere
