Transient Pressure-Relief Characteristics of Ethylene/Vinyl Acetate Mixtures in the High-Pressure Polyethylene Process
Pressure relief in high-pressure polyethylene processes involves dense, strongly non-ideal ethylene-based fluids. A transient real-fluid model was developed for the single-phase discharge of ethylene/vinyl acetate (VA) mixtures by coupling adiabatic vessel depressurization with quasi-steady isentropic nozzle flow.
