← ScienceWhich risk notably increases when a pressurized gas vessel’s molecular sieve becomes saturated?
A)Catalyst poisoning occurs unexpectedly
B)Reduced motor efficiency develops rapidly
C)Overpressure damage causes vessel rupture✓
D)Polymer degradation increases drastically
💡 Explanation
Overpressure damage increases because the adsorption mechanism fails, preventing removal of contaminant molecules; gas pressure builds rather than being regulated; therefore, rupture risk rises because pressure exceeds vessel rating, rather than alternative causes during normal operation.
