Equations of hydraulic parameters such as pressure drop,weeping and entrainment were regressed.

The results show that HEFV tray possesses a little higher pressure drop,less entrainment,lower weeping and higher efficiency than sieve tray as well as lower pressure drop,less entrainment,higher weeping and higher.

The results showed that the half-ellipse fixed valve tray possessed,less entrainment,lower weeping and higher efficiency,but a little higher pressure drop than sieve tray as well as much lower pr.
