Channeling occurs when a fluid flowing through a bed is not evenly dispersed throughout the bed. For instance large diameter reactors have more frequent channeling problems where liquid is prone to channel along the reactor walls. Channeling should be avoided and reduces efficiency and conversion since reactants do not have proper contact with catalysts or separation media.

What is circulating fluidized bed boiler?
A circulating fluidized bed boiler helps to hold fuels in a solid states in upwards air jets when combustion occurs. This creates a mixture of unstable solids and gasses, which can promote chemical processing.
What is the channeling in distillation column?
In distillation coloum the channeling means is the unequal wetting of the packings in the tower. If channeling occurs, poor mass transfer happens, and therefore, less efficiency of the tower happens. AWAIS AFRIDI DEPARTMENT OF CHEMICAL ENGINEERING UNIVERSITY OF GUJRAT...
What is flooding and channeling in context with distillation?
Flooding and channeling are very significant terms with both gas absorption and distillation of it involves the use of packed towers. Flooding means that the gas velocity is very high, therefore, does not allow the flow of the liquid from the top of the tower, and flooding occurs on the top of it (ergo, the gas phase is not completely mixed by the water phase). The best gas velocity, should be half of the flooding velocity. For channeling, it is the unequal wetting of the packings in the tower. If channeling occurs, poor mass transfer happens, and therefore, less efficiency of the tower happens.
What is water breakthrough?
water breakthrough is concerned with oil production wells. when a layer of water under the oil layer channeling into the oil accumulation, it called water breakthrough or water coning phenomena.
Fluidized media reactor?
It is a single tank unit, consisting of a bar screen chamber, specially designed floating media to facilitate the attached growth process, oxygen transfer through diffused membrane aeration, lamella settler and chlorine contact tank. The system is available in mild steel and reinforced concrete. These systems are using for "WASTE WATER TREATMENT". Mahipal Reddy M Ionexchange Services lmtd Ph- +91 9986953011

What is afbc boiler?
Atmospheric Fluidized Bed Combustion Boiler (AFBC boiler) is a type of operational boiler. In a AFBC boiler a little more fluidized bed combustor is added than a conventional shell boiler.
