Where are fluidised bed reactors used?
chemical processing industries
Fluidized bed reactors are the most popular configurations employed from laboratory to commercial scale. These reactors are widely used in petroleum and chemical processing industries. Fluidized bed reactors are more efficient because the feedstock input and bio-oil production are continuous.
What are the advantages of fluidised bed reactor?
Fluidized-bed reactors offer a much higher efficiency in heat exchange, compared to fixed beds, and better temperature control, due to the turbulent gas flow and rapid circulation. At the same time, the high gas velocities do not cause any pressure drop issues and smaller catalyst particles can be employed.
What does a fluidised reactor do?
Fluidised bed reactors provide biological filtration very similar to that provided by under gravel filters. Nitrifying bacteria colonies grow on the surface of the particles of sand in the bed, and process ammonia and nitrite into nitrate as the water passes through the filter.
Why plug flow reactor is better than CSTR?
A PFR has a higher theoretical efficiency than a CSTR of the same volume. That is, given the same space-time (or residence time), a reaction will proceed to a higher percentage completion in a PFR than in a CSTR.
What is fluidised bed used for?
Fluidized beds are used for several purposes, such as fluidized bed reactors (types of chemical reactors), solids separation, fluid catalytic cracking, fluidized bed combustion, heat or mass transfer or interface modification, such as applying a coating onto solid items.
What are the disadvantages of fluidized bed reactors?
Disadvantages. As in any design, the fluidized bed reactor does have its draw-backs, which any reactor designer must take into consideration. Increased reactor vessel size: Because of the expansion of the bed materials in the reactor, a larger vessel is often required than that for a packed bed reactor.
What are fluidised beds used for?
What are the disadvantages of fluidized bed reactor?
There are a few disadvantages to using fluidized beds. Due to the expansion of the materials in the reactor, the size of the vessel must be increased, which leads to a higher initial capital cost. Also, because the fluidized material is solid, this leads to some erosion of the components inside.
How do you calculate the volume of a packed bed reactor?
Popular Answers (1)
- Space velocity = flow rate of the reactants/ the reactor volume.
- GHSV =Hourly volumetric feed gas flow rate/reaction volume.
- LHSV= Hourly volumetric feed liquid flow rate/reaction volume.
- WHSV=Hourly mass feed flow rate/ Catalyst mass.
