← ScienceWhich outcome occurs when cryogenic storage of LNG reaches saturation?
A)Vapor-Liquid equilibrium establishes, decreasing heat
B)Excessive expansion, risking tank structural overload✓
C)Methane clathrate formation blocking tank vents
D)Increased fluid density causing gauge errors
💡 Explanation
Excessive expansion risks structural overload because *isenthalpic expansion* of vaporized LNG causes a large density increase and thus pressure overwhelms safety margins; therefore, a cryogenic tank risks rupture rather than equilibrium, due to rapid phase changes in a closed system.
