Slurry bubble column
Did you know?
Bubble column reactors are used in various types of chemical reactions like wet oxidation, or as algae bioreactor. Since the computerized design of bubble columns is restricted to a few partial processes, experience in the choice of a particular type column still plays an important role. Visa mer A bubble column reactor is an apparatus used to generate and control gas-liquid chemical reactions. It consists of a vertically-arranged cylindrical column filled with liquid, at the bottom of which gas is inserted. Visa mer The introduction of gas takes place at the bottom of the column and causes a turbulent stream to enable an optimum gas exchange. Numerous forms of construction exist. The mixing is done by the gas sparging and it requires less energy than mechanical … Visa mer 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), … Visa mer • Modeling of mass transfer characteristics of bubble column reactor with surfactant present Visa mer Webb1 jan. 2003 · Slurry bubble column reactors are presently used for a wide range of reactions in both chemical and biochemical industry.
