Which effect occurs when rapid depressurization causes a two-phase fluid consisting of liquid butane within a processing plant distribution line?

💡 Explanation

Temperature drop occurs because the Joule-Thomson effect causes an isenthalpic expansion with vaporization during rapid depressurization; therefore rapid auto-refrigeration drops temperature drastically, rather than allowing normal phase equilibrium or increased pressures.
