← ScienceWhich outcome occurs when an adiabatic flash drum receives a high-enthalpy liquid stream with insufficient residence time?
A)Reduced vapor-liquid equilibrium is achieved✓
B)Increased bottoms volumetric flowrate arises
C)Azeotrope formation prematurely happens then
D)Supercritical fluid separation spontaneously occurs
💡 Explanation
Reduced vapor-liquid equilibrium occurs due to insufficient residence time for phase change. Rate-limited mass transfer is the mechanism whereby equilibrium cannot fully establish because the liquid stream passes through too rapidly; therefore, the composition in the phases deviate from ideal equilibrium assumptions rather than alternatives such as flow rates.
