The required vent area for pressure relief equipment is affected by the gas/vapor-liquid disengagement. The main objective of this work is the experimental verification of disengagement models for highly viscous fluids. The dynamic two-phase flow in the vessel is modeled with a one dimensional finite volume approach, the phase slip is taken into account with a drift flux model recommended by DIERS. The simulation shows good agreement with the experiment if the drift velocity is considered as a function of the fluid phase viscosity.
