Mass-Transfer Efficiency of a Large-Scale Sieve Tray Extractor
The mass transfer efficiency and phase flow capacity of a 42.5-cm-diameter (i.d.1 sieve tray extractor has been investigated. The extraction of acetone from water with toluene was chosen because of the large amount of data for comparison with the performance of other devices, and particularly because of available data for a smaller sieve tray extractor tested in the same laboratory. For capacit...
متن کاملHeat and Mass Transfer Characteristics of an Annular Sieve Tray
An internally heat integrated distillation column, HIDiC, offers the maximum energy saving potential for difficult and energy intensive separations, such as propylenepropane and the like, which are carried out in tray columns. A novel type of HIDiC was developed by TUDelft, namely a concentric distillation column in which a low pressure annular stripping section is configured around a high pres...
متن کاملMass Transfer Coefficients in Pulsed Perforated-plate Extraction Columns
This study examined the mass transfer performance in a pulsed perforated-plate extraction column with diameter of 50 mm using two different liquid systems. Mass transfer coefficients have been interpreted in terms of the axial diffusion model. The effects of pulsation intensity and dispersed and continuous phase velocities on the mass transfer performance have been investigated. Three different...
متن کاملHeat Transfer Study of Perforated Fin under Forced Convection
Fins are protrusions on a heat transfer surface to augment heat transfer rate from it. The increase in area exposed to convection in case of finned surfaces results in increased heat transfer rate. In this study heat transfer characteristics of a pin fin with perforation is numerically analyzed. A pin fin is fabricated and experiments are done under forced convection conditions. The experimenta...
متن کاملHeat-Transfer Enhancing Features for Handler Tray-Type Device Carriers
Many test handlers process semiconductor devices in trays which must be rapidly heated or cooled by a forced air flow to a desired test temperature and then back to ambient temperature. This paper describes a new design feature for testhandler tray that significantly increases the rate of convective heat transfer to the tray and the devices in the tray. The improved tray incorporates lateral ri...
