What is the purification efficiency achievable through activated carbon adsorption? !
Thread Content
The purification efficiency of activated carbon adsorption is quite high. I heard a claim today that the purification efficiency of activated carbon has nothing to do with the concentration of waste gases. According to this claim, as long as the activated carbon bed is tall enough, the purification efficiency can reach 100%? ! Is this claim a lie? ! It must be closely related to concentration, right? ! Thank you! !
For example: you want to separate a binary substance—carbon three from carbon four. With a fixed number of trays, the higher the requirement at the top of the tower (e.g., 99.99%), the greater the reflux will be, and consequently there will be a certain amount of C3 at the bottom of the tower. The principles are more or less the same.
Umm~~~ I don’t understand this example. . . What do you mean?
Activated carbon adsorption is a dynamic equilibrium; how can the purification efficiency reach 100%?
Same question: what is the general adsorption efficiency of activated carbon? % represents the adsorption efficiency, not the adsorption capacity
With physical adsorption, the efficiency inevitably decreases over time, which then requires regeneration or replacement.
Our company uses activated carbon to absorb THF molecules from gases, and the efficiency follows a certain curve: it is 100% within 10 minutes, but if the concentration is three times normal, absorption is no longer possible after 5 minutes.
There is no such thing as 100%. At most, it cannot be detected.
The accuracy of the analyzer is 0.1 ppm
The ppm unit is usually larger than mg!
