A bubble column reactor is a chemical reactor that belongs to the general class of multiphase reactors, which consists of three main categories: trickle bed reactor (fixed or packed bed), fluidized bed reactor, and bubble column reactor. [1] A bubble column reactor is a very simple device consisting of a vertical vessel filled with water with a ...
Representation of a bubble column reactor. Ranade has worked on various aspects of fluid dynamics such as multiphase flows and Reactors, computational flow modelling and process intensification and has developed Computational fluid dynamics models with regard to various types of reactors like bubble column, stirred and trickle bed varieties.

Biological methanation in a pressurized reactor vessel (in-situ process). Pressure allows for better hydrogen solubility and therefore easier conversion into methane by microorganisms. [10] A possible reactor configuration can be Autogenerative high-pressure digestion. Research in Korea has demonstrated that 90% > CH4, 180 MJ/m3 biogas can be ...
Vertical bubble columns, a project at the Universidad EAFIT to utilize algae to reduce CO 2 emissions. A bubble column photo reactor consists of vertically arranged cylindrical columns made out of transparent material. The introduction of gas takes place at the bottom of the column and causes a turbulent stream to enable an optimum gas exchange.
Another experiment studies the bubbling gas-solid fluidization in a 0.05 ID column, where the solid holdup, bubble shape and frequency obtained from ECT are validated with MRI measurements. [24] The flexibility of the 3D ECT sensor geometry also enables it for imaging of bend, tapering and other non-uniform sections of gas-solid flow reactors.
The circulating catalyst process can be replaced by fluid-bed technology. Early experiments with cobalt catalyst particles suspended in oil have been performed by Fischer. The bubble column reactor with a powdered iron slurry catalyst and a CO-rich syngas was particularly developed to pilot plant scale by Kölbel at the Rheinpreuben Company in ...
An example of a bubble cap tray that could be found inside of a stripping column. Stripping is mainly conducted in trayed towers (plate columns) and packed columns, and less often in spray towers, bubble columns, and centrifugal contactors. [2] Trayed towers consist of a vertical column with liquid flowing in the top and out the bottom.
A real plug flow reactor has a residence time distribution that is a narrow pulse around the mean residence time distribution. A typical plug flow reactor could be a tube packed with some solid material (frequently a catalyst). Typically these types of reactors are called packed bed reactors or PBR's.
