← ScienceWhich outcome results when rapid depressurization causes adiabatic cooling in natural gas pipelines?
A)Hydrate formation initiates blockage✓
B)Increased pipeline material tensile strength
C)Reduced methane combustion heating value
D)Enhanced gas flow rate equilibrium
💡 Explanation
Because adiabatic cooling lowers the gas temperature significantly, the process causes hydrate formation, a complex phase transition. Therefore, hydrates, rather than strength increases occur, because the cooler conditions favor crystallization rather than kinetic energy transfer.
