Research on the phase separation characteristics of gas-liquid separator using surface tension

摘要

In this study, a novel gas-liquid separator using surface tension is proposed and the performance is evaluated by air-water experiment. Two major limits of gas-liquid separation, i.e. (1) flooding limit in high liquid flow rate region and (2) entrainment limit in high gas flow rate region, are investigated by flow rate measurement and flow visualization. Finally, empirical correlations for both separation limits are proposed. Furthermore, guidelines to design a high-performance gas-liquid separator are discussed.
