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 ...
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.
Schematic diagram of an RBMK Schematic side view of the layout of an RBMK reactor core The reactor hall and piping systems of the RBMK reactor. The reactor pit or vault is made of reinforced concrete and has dimensions 21.6 m × 21.6 m × 25.5 m. It houses the vessel of the reactor, which is annular, made of an inner and outer cylindrical wall ...
The groups are defined by their locations on a diagram of solid-fluid density difference and particle size. Design methods for fluidised beds can be tailored based upon the particle's Geldart grouping: [11] Group A For this group the particle size is between 20 and 100 μm, and the particle density is typically less than 1.4g/cm 3. Prior to the ...
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 fluidized bed reactor (FBR) is a type of reactor device that can be used to carry out a variety of multiphase chemical reactions. In this type of reactor, a fluid (gas or liquid) is passed through a solid granular material (usually a catalyst) at high enough speeds to suspend the solid and cause it to behave as though it were a fluid.
These experimental designs (all of which shared the BWR-1 classification despite their divergent designs) used fuel rod bundles in 6×6, 7×7, 8×8, 9×9, 11×11, and 12×12 configurations, but GE's 9×9 bundle later used in BWR/2–6 reactors is different from the one used in the BWR/1 era. [2]
One reactor with a capacity of 500,000 tons per annum is in operation. The process has been used for C 2 and C 7 alkene production. A high-temperature process with a circulating iron catalyst ('circulating fluid bed', 'riser reactor', 'entrained catalyst process') was introduced by the Kellogg Company and a respective plant built at Sasol in 1956.
