Abstract�� The pressure drop and separation efficiencies were measured and analyzed in a �v300 mm single-path rotating-stream tray(RST) separator and a double-path RST separator.The pressure drop of the double-path RST separator decreased by 12.8% of that of the single-path RST separator.For the double-path RST separator,the workable gas velocity range was greatly increased,and no significant effects of gas velocity and spray density on separation efficiency and entrainment were observed,and the separation efficiencies were above 99.9% within the experimental range.When the tray vane exit velocity varied from 10 m/s to 17 m/s,the amount of mist escaped from the double-path RST separator decreased by 72.7% to 96.3% of that from the single-path RST separator.The advantages of double-path RST separator over single-path RST separator are the integrated effects of increased tangential velocity,elimination of the vortex rings in most axial plane region,and the decreased separation distance.
