← ScienceWhich outcome occurs when rapid depressurization causes wet natural gas to cool?
A)Hydrate formation and pipeline blockage✓
B)Increased gas viscosity remains unchanged
C)Refrigeration reduces liquid nitrogen presence
D)Higher temperatures with less oxygen separation
💡 Explanation
Hydrate formation plugs depressurized pipelines because the Joule-Thomson effect causes cooling during expansion, promoting hydrate formation from water and methane, rather than the gas remaining stable; therefore blockage occurs.
