Slurry Reactor: Mass Transfer Considerations
The bioreduction of solid TNT by a Pseudomonas fluorescens strain was investigated in a stirred tank reactor. Experiments in which TNT beads were the only solids present indicated that the biodegradation mechanism is dissolution followed by degradation in bulk solution. Dissolution may limit the overall rate, in which case degradation can be enhanced through increased agitation. Since soil slur...
متن کاملHydrodynamics and mass transfer inthree-phase airlift reactors for activated Carbon and sludge filtration
A bioreactor refers to any manufactured or engineered device that supports a biologically active environment. These kinds of reactors are designed to treat wastewater treatment. Volumetric mass transfer coefficient and the effect of superficial gas velocity, as the most important operational factor on hydrodynamics, in three-phase airlift reactors are investigated in this study. The experiments...
متن کاملMass Transfer Studies in Shallow Bubble Column Reactors
Mass transfer studies are carried out in a bubble column with an internal diameter of 14 cm and various static liquid heights. The mass transfer coefficient is evaluated by using an oxygen sorption method. A model considering the gas holdup flushing and the sensor response is used. The interfacial mass transfer area is determined according to the measured bubble size distribution. The liquid-si...

Multiplicity of steady states was experimentally obser®ed, somewhat sporadically, for ( ) Fischer Tropsch FT synthesis in stirred tank slurry reactors in the reactor originally ( ) at the wax-producing normal steady state suddenly jumping to a high-temperature ( ) methane-producing steady state for some time and e®entually returning to the normal steady state. A diagnostic nonlinear analysis sh...
متن کاملApplication of New Inflection Point Method for Hydrodynamics Study in Slurry Bubble Column Reactors
Bubble column reactors are used in a wide variety of applications such as multiphase bioreactors, catalytic slurry reactors, and absorption processes. The superficial gas velocity-gas holdup relationship and transition point are two important parameters for characterizing the hydrodynamics of a bubble column reactor. In this study, systematic investigation of a nitrogen - water - glass bead...
