Bubble column definition and meaning | Collins English ...

A bubble column is a reactor in which a gas bubbles up through a liquid or slurry. In a bubble column , mixing is provided by the upward velocity of the bubbles. A bubble column is a device in which a gas phase is injected through a column of liquid to promote a chemical or biochemical reaction.

Bubble Column Reactor | Chemical Reaction Engineering ...

Bubble column reactors belong to the general class of multiphase reactors which consist of three main categories namely, the trickle bed reactor (fixed or packed bed), fluidized bed reactor, and the bubble column …

Column Packing for Process-Scale Chromatography ...
