Bubble Column - an overview ScienceDirect Topics

The flow pattern of bubbles through a bubble column reactor is dependent on the gas superficial velocity (volumetric air flow rate/cross sectional area of the vessel, cm second –1).At gas velocities of below 1–4 cm s –1 the bubbles will rise uniformly through the medium (Van’t Riet Tramper, 1991) and the only mixing will be that created in the bubble wake.

Modeling of CO2 Capture with Water Bubble Column

Another potential solvent for CO2 could be water, which is easily available and safe to use in many applications. The problem with water is the poorer solubility of CO2, compared with amines, which leads to larger required flow rates. This study analyzed the technical feasibility of water absorption in a counterflow bubble column reactor.
