Flow through Packed Beds and Fluidized Beds
Chemical engineering operations commonly involve the use of packed and fluidized beds. These are devices in which a large surface area for contact between a liquid and a gas (absorption, distillation) or a solid and a gas or liquid (adsorption, catalysis) is obtained for achieving rapid mass and heat transfer, and particularly in the case of fluidized beds, catalytic chemical reactions. You wil...

متن کاملFlow Pattern Identification and Pressure Drop Calculation for Gas-Liquid Flow in a Horizontal Pipeline
Two phase gas-liquid flow pattern in a horizontal pipeline is predicted very accurately using a newly-developed analytical relation. The pattern identification is based on one of the most widely used graphs, the Baker diagram, modified in a way that compensates for the unrealistic oversimplifications of recent works. The Kern's method of pressure drop calculation is used to obtain the frict...
متن کاملNMR Imaging of Water Flow in Packed Beds
Measurements by magnetic resonance imaging (MRI) of water flow within granular porous media are presented in this study. Our goal was not only to obtain visualizations of velocity field in porous media but rather to make accurate measurements of interstitial and averaged velocities in bead packs. Two situations were examined: the first for a packed bed with a large beads diameter where it was p...
متن کاملParameters characterising the pulsing flow for cocurrent flow of gas and foaming liquid in a pressurised trickle-bed reactor
The aim of the present work was to experimentally determine the parameters characterizing the pulse flow of liquids through bed i.e. the frequency of pulsation and the velocity of pulses travelling along the bed and next to work out the correlation equations enabling their assessment. The research was carried out in a pressure reactor (pressures up to 2 MPa) having 0.05 m in diameter and being ...
