A Study on Sieve Tray Lower Operating Limit
Sieve trays are widely used fractionating devices in separation and purification industries involving tray towers. According to the importance of trays, it is vital to predict lower operating range limits for such gas-liquid contacting devices. Weeping phenomenon observed in bubbling regime and occurs at low vapor flow rates. The experimental set up includes a 1.22 m diameter column with two te...
متن کاملEffect of Inlet Downcomer on the Hydrodynamic Parameters of Sieve Trays Using CFD Analysis
Nowadays distillation is recognized as one of the economical and the most trustable separation methods in chemical, petroleum, gas and petrochemical industries. It is almost used as a first and the most applicable choice in separation methods. In this article the effect of inlet downcomer on the hydrodynamics of industrial sieve tray has been elaborated. The study was carried out by using a 3-D...
متن کاملSieve Estimators : Consistency and Rates of Convergence
The first term is the estimation error and measures the performance of the discrimination rule with respect to the best hypothesis in H. In previous lectures, we studied performance guarantees for this quantity when ĥn is ERM. Now, we also consider the approximation error, which captures how well a class of hypotheses {Hk} approximates the Bayes decision boundary. For example, consider the hist...

متن کاملHydrodynamics of Sieve Tray Distillation Column Using CFD Simulation
Sieve trays are widely used in the gas- liquid contactors such as distillation and absorption towers. In this article, a three-dimensional, two phase CFD model using Euler-Euler framework was developed to simulate a distillation tower with two sieve trays. Hydrodynamic simulation of air and water system in different rates of gas phase was carried out and velocity distribution parameters, clear ...
