What is breakthrough in fixed bed adsorption?
A breakthrough curve in adsorption is the course of the effluent adsorptive concentration at the outlet of a fixed bed adsorber Breakthrough curves are important for adsorptive separation technologies and for the characterization of porous materials.
What is breakthrough in adsorption?
Breakthrough occurs when adsorbate reaches the end of the column and leaves with the column effluent. Breakthrough curves are plots of the adsorbate concentration in the column effluent as a function of time.
What do breakthrough curves show?
The breakthrough curve illustrates the behavior of a fixed-bed column from the point of view of the pollutant quantity that can be retained and is usually expressed in terms of a normalized concentration defined as the ratio of the effluent metal concentration to inlet concentration, as a function of flow time or …
How is breakthrough concentration defined for adsorption in packed bed?
b) 1000 bar. c) 2000 bar. d) 10000 bar. 7) How is the breakthrough concentration defined for adsorption in a packed bed? a) It is the minimum detectable or maximum allowable concentration in the effluent from the bed.
How are breakthrough curves used in dynamic sorption?
In a dynamic sorption process, you can address several scales. Therefore, the result of such an experiment, the breakthrough curve, contains information about these different scales. Different scales which influence the adsorption under dynamic conditions.
What kind of adsorbent is used in breakthrough curve?
A granular carbonaceous activated adsorbent produced by carbonization of the outer rind, or exocarp, of mangostene fruit shell was used for column packing. The effects of feed flow rate, influent cation concentration, and bed depth on the breakthrough curve were investigated at pH 5.5.
How does feed flow rate affect the breakthrough curve?
The effects of feed flow rate, influent cation concentration, and bed depth on the breakthrough curve were investigated at pH 5.5. Experimental analysis confirmed that the breakthrough curves were dependent on flow rate, initial concentration of Cu (II) cations, and bed height related to the amount of activated carbon used for column packing.
Which is the best definition of a breakthrough curve?
As already discussed ( Dynamic Sorption ) a breakthrough curve is an interplay of different kinetic and thermodynamic effects.
