Is activated carbon mainly used for VOC control? !
Thread Content
Is there also a biological method? ! Thank you. . . . . .
Incineration, activated carbon adsorption, low-temperature plasma, photocatalytic oxidation, ozonation, water and acid-base washing, adsorption and desorption using high-boiling-point solvents
Okay, thank you. . . . Which one is the most mainstream? !
You also need to consider the actual situation of your company to determine which approach is suitable. It can be done through adsorption, incineration, alkaline washing, condensation – there are various methods available, depending on the company’s financial conditions
Okay, thank you. . . . . .
The most commonly used methods today are activated carbon adsorption and catalytic combustion. However, activated carbon merely transfers pollutants, and there is also the issue of dealing with this activated carbon; such methods should gradually be phased out. Therefore, the catalytic combustion method is more feasible.
Treatment after activated carbon adsorption is more complicated, so it is gradually being phased out.
Okay, thank you. . . . . . .
In fact, isn’t most of what’s done in environmental protection these days just the transfer of pollutants? ! !
Activated carbon is absolutely not suitable; it’s obsolete, unless it’s an RTO
His answer was also incomplete. It depends on the type and concentration of VOC gases, whether they have value for recovery, and whether they can be adsorbed, etc. 1. For high-concentration single components, adsorption can be used for recovery, followed by desorption to obtain the product ； 2. For high-concentration complex components, adsorption can be used for recovery, followed by incineration ； 3. For low-concentration, complex-component, large-volume VOCs, zeolite rotary wheels can be used for concentration, followed by incineration using RTO/RCO ； 4. For low concentrations and small amounts of VOCs, there are many treatment methods available; activated carbon adsorption, low-temperature incineration, photoionization methods, biological methods, and so on can all be used for treatment.
