About this site

Bubble Column Reactors are used in various types of chemical reactions like wet oxidation, or as algae bioreactor. Introduction of gas takes place at the bottom of the column and causes a turbulent stream to enable an optimum gas exchange. Bubble column is particularly useful in reactions where the gas-liquid reaction is slow in relation to the absorption rate.

BUBBLE COLUMN REACTOR. INTRODUCTION A bubble column reactor is an apparatus used for gas-liquid reactions first applied by Helmut Gerstenberg. It consists of vertically arranged cylindrical columns. The introduction of gas takes place at the bottom of the column and causes a turbulent stream to enable an optimum gas exchange. It is built in numerous forms of construction.

Bubble column reactors. Basic set up • Structured catalytic bubble columns are new, very promising types of multiphase reactors. • Their configuration lies basically between slurry reactors and trickle bed reactors. • The solid phase, consisting of catalyst particles, is enclosed in fixed wire gauze wraps, which are mounted along the height of the column.

Jun 29, 2012 · 4. Bubble Columns Gas is sparged at the bottom of the liquid pool contained by the column. The net liquid flow may be co-current or counter- current to the gas flow direction or may be zero. Spargers, like porous plates, generate uniform size bubbles and distribute the gas uniformly at the bottom of the liquid pool. 5.

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.
