Bubble column reactor

 · A bubble column reactor is basically a cylindrical vessel with a gas distributor at the bottom. The gas is sparged in the form of bubbles into either a liquid phase or a liquid–solid suspension. These reactors are generally referred to as slurry bubble column reactors when a solid phase exists.

Bubble Column

The bubble column reactors represent contactors in which a gas or a mixture of gases is distributed in the liquid at the column bottom by an appropriate distributor and moves upwards in the form of bubbles causing intense mixing of the liquid phase.

Bubble column reactor

Literature. 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 reactor. Bubble columns are the devices in which gas, in the form of bubbles, come in contact with the liquid.
