← ScienceWhich outcome occurs when rapid depressurization causes hydrocarbon fluid phase transition inside a pipeline?
A)Formation of gas hydrates obstructing flow✓
B)Increased fluid viscosity due to polymerization
C)Pipeline corrosion from acid condensation
D)Pressure surge from sudden volume change
💡 Explanation
When pressure drops rapidly, the hydrocarbon fluid undergoes a phase change potentially forming solid gas hydrates because lower pressures favor gas formation, especially in the presence of water causing flow restriction. Therefore hydrates form rather than polymerization, corrosion, or surges which depend on different chemical or mechanical mechanisms.
