← ScienceWhich outcome occurs when rapid hydrocarbon vapor depressurization exists?
A)Auto-refrigeration results in hydrate formation✓
B)Increased catalytic activity reduces efficiency
C)Material embrittlement prevents further expansion
D)Oxidation stability decreases significantly immediately
💡 Explanation
Auto-refrigeration results from *isenthalpic expansion* because energy remains constant; therefore, temperature drops, causing hydrates to form. This is because depressurization cools the vapor, rather than increasing catalytic activity and other scenarios occur in different operating conditions.
