← ScienceWhich risk increases when ammonia synthesis plants experience hydrogen embrittlement?
A)Catalyst thermal runaway events rise
B)Compressor seal failures accelerate rapidly
C)Reaction vessel fracture probability increases✓
D)Product contamination from inert gases
💡 Explanation
Hydrogen embrittlement weakens the steel reaction vessel because hydrogen atoms diffuse into the metal lattice, reducing ductility; therefore the risk of fracture increases, rather than directly affecting the catalyst, compressor, or product purity under increased pressure.
