Radial Liquid Dispersion in Gas-Liquid Cocurrent Flow through Packed Beds

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...

Parameters 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 ...

Heat Transfer Mechanisms in a Gas – Liquid-Solid Fluidized Beds

Three-Phase Fluidized Beds have found an important place in processing technology as Reactors. Gas-Liquid-Solid fluidization is considered in the present paper as operating bed of fluidized solid particles simultaneously with co-current upward flow of a continuous liquid phase and a gaseous phase dispersed in the form of bubbles. In the present study, the experimental work of the author on heat...
