A Study on Hydrodynamics of Large holed Combination Sieve Tray in Spray Regime

In this thesis, hydrodynamic data of large hole area and large holed sieve trays in spray regime were obtained and studied. A set of equations to correlate hydrodynamic parameters was established. As a result, the combination sieve tray had the characteristics of lower resistance, little entrainment and big upper limit velocity of operation. Especially, it was agrees with the fact that the processes require a large gaseous phase loading and lower liquid loading.
