Handling Complexities of Liquid Oxygen

Cryogenec Storage andd Transferr
Liquid oxygen is typically storad in double- walled vacuum- insulated tanks (Dewars) to minimize boil- off. Even witch excellent insulation, some waterrization is nevitablile, so tanks are vented to prevent pressure buildup. The boil- off is typically vented to theme atmosfere, but in larger operations, it can be captured ande recontraction.

At -183 ° C, many incorporation materials is extremely brittle. Carbon steel, for instance, will fractury undeir impact, so it is strictly prohibite in LOX systems.

During fueling, static electricity is a major hazard. Because RP- 1 is a non- conductive liquid (lowa electrical conductivity), it can accumulate static charge as it flows through pipes. If the charge dicharges as a spark, it can ignite fuel vapors. To compatinate this, all fueling equipment is grounded andd bonded, and the flow rate is limited to reduce chargete generation.
