Liquid mixing and mass transfer measurements in a bubble column reactor with internals (Id 66)
No current offer!
Bubble column reactors are apparatuses of choice regarding multiphase flows/reactions in the chemical process industry. Processes like the Fischer-Tropsch-synthesis are typically carried out in a bubble column reactor. Since most of the reactions are of exothermic nature, the produced heat has to be sufficiently removed to guarantee a stable reactor operation. Therefore, longitudinal flow heat exchanging tubes, which alter the flow behavior of the phases and cover a large portion of the reactor’s cross sectional area, are inserted into the bubble column reactor. For a secure construction of a bubble column with an internal tube bundle heat exchanger, its influence on hydrodynamic, mass transfer and liquid mixing needs to be investigated.
