Dynamic Zero-Net Liquid Holdup in a Gas-Liquid Cylindrical Cyclone (GLCC(c)) Separato

Better understanding of Liquid Carry-Over (LCO) is important for the proper operation of Gas-Liquid Cylindrical Cyclone (GLCC(c)) separators. Zero-Net Liquid Holdup (ZNLH) is a critical factor for the prediction of LCO. ZNLH is studied using static and dynamic experimental methods. A new correlation is developed based on Wallis' ( 1961) "Flooding and Reverse Flow" correlation to predict the dynamic ZNLH.;Novel experimental data are acquired in a 3" diameter GLCC (c) for air-water and air-oil flows using both static and dynamic experimental methods. The liquid level is maintained at 6" below the GLCC inlet.;Air-oil flow exhibits higher liquid holdup than air-water flow for both static and dynamic ZNLH. Comparison of static ZNLH data and dynamic ZNLH data show lower liquid holdup for dynamic ZNLH as compared to static ZNLH results for both air-water and air-oil flows.;A correlation is developed for predicting dynamic ZNLH based on the "Flooding and Flow Reversal" model by Wallis ( 1961). The correlation developed accounts for the effect of viscosity and surface tension. The correlation is in good agreement with the acquired experimental data. Uncertainty analysis is performed on the dynamic ZNLH data showing a maximum uncertainty of +/-15% in the experimental results.
