| Abstract: | The hydrodynamic characteristics of a high efficient flow guided sieve tray with pores of Φ6mm were investigated in a test column of Φ 600mm using an air water system at atmospheric pressure. Experimental data of the tray pressure drop, weeping and entrainment rates were obtained, correlated and analyzed. A correlation of the dry tray pressure drop and the total pressure drop was provided. The effects of the flow rate and pore velocity on the entrainment and weeping were discussed. The experimental results will be helpful for the design of a high efficient flow-guided sieve tray |

| Keywords: | high efficient flow-guided sieve tray hydrodynamic pressure drop entrainment weeping |
