Why should we use Activated Carbon for VOC Removal?
VOC is the abbreviation of Volatile Organic Comounds, which usually refers to organic compounds that are easily volatile at room temperature. The more common ones are benzene, toluene, xylene, ethylbenzene, styrene, formaldehyde, TVOC (alkanes with 6-16 carbons), ketones, etc. VOC is widely used in chemical, paint, printing, pharmaceutical and other industries.
VOCs have a low boiling point and are easy to evaporate. Once they reach the atmosphere, when the atmospheric temperature is lower than the boiling point, VOCs will condense and reliquefy, returning to the ground through rain or snow and then flowing into the water supply system.
Harm to Human Health
If VOCs enter drinking water without being adequately filtered, they will be ingested by the human body and cause great harm to human health. They can damage the liver, kidneys, brain and nervous system, and may even cause organ failure or cancer.
Harm to the Environment
VOCs also affect climate change and cause plant decay. A study by the National Academy of Sciences of the United States claims that the release of chlorofluoromethane and chlorine-containing compounds into the atmosphere can cause infrared radiation, which in turn causes global climate change.
Activated carbon has a highly developed pore structure, a large specific surface area and unique physical and chemical properties. It has been proven to be a very effective method for removing VOCs. Heycarbons activated carbon can solve your VOC emission problems.
How to use Activated Carbon for VOCs Removal - Activated Carbon Filter for VOCs Removal
Activated carbon voc removal efficiency is 25%-50%. If you want to know how to use activated carbon for VOC removal, you can learn about three kinds of adsorption device of activated carbon filter for VOC removal below. The pictures below show the activated carbon filter for VOC removal.
Fixed Bed
Suitable for treating VOC waste gas with low concentration (<1000ppm) and medium air volume. The waste gas passes through the dehumidification section, adsorption section and desorption section in turn. The VOCs in the waste gas are intercepted by the activated carbon, and the purified gas meets the emission standards. After the activated carbon is saturated, it is regenerated by hot air or steam to release VOCs and restore the adsorption capacity of the activated carbon, thereby achieving continuous operation.
- Advantages: simple structure, easy operation and maintenance, suitable for the treatment of low-concentration VOC.
- Disadvantages: When treating large air volume gas, the device is large in size, and a short regeneration cycle may lead to high energy consumption.
Moving Bed
Suitable for the treatment of VOC waste gas with high concentration (>1000ppm) and large air volume. The activated carbon is in countercurrent contact with the waste gas and circulated through the adsorption, desorption and regeneration process. The activated carbon is regenerated by high temperature or steam to release VOC.
- Advantages: The activated carbon participates in the adsorption process in a dynamic form, fully contacts with the waste gas, and has high purification efficiency.
- Disadvantages: Large equipment investment, strict process control requirements, and relatively high operation and maintenance costs.
Honeycomb Rotor
Suitable for the treatment of VOC waste gas with high concentration and large air volume. The honeycomb activated carbon rotates slowly through the rotor, and contacts with the waste gas in countercurrent, and VOCs are adsorbed on the surface of the activated carbon. After the rotor is saturated with adsorption, microwave or electric heating is used for desorption, and the regenerated pyrolysis gas enters the RTO (catalytic combustion furnace) for incineration.
Advantages:
- This process integrates adsorption, desorption and catalytic combustion, which can effectively reduce VOC emissions.
- Small wind resistance, stable operation, suitable for high concentration and large air volume waste gas treatment.
Disadvantages: The system cost is high, and the investment in equipment and operation is large.
Activated Carbon VOC Removal Efficiency Factors
Activated carbon voc removal efficiency is 25%-50%. There are several factors which affect activated carbon voc removal efficiency:
- VOC Concentration: Higher VOC concentrations generally result in increased rates of adsorption.
- VOC Molecular Weight: Larger molecules tend to be adsorbed more readily than smaller molecules.
- Activated Carbon Type: Pelletized anthracite has high strength and strong adsorption capacity.
- Carbon Surface Area: Activated carbons with larger surface areas have greater adsorption capacity.
- Carbon Pore Size: The pore size distribution of the carbon must be compatible with the size of the VOC molecule.
- Temperature and Humidity: Lower temperatures and lower humidity can enhance adsorption.
- Air Flow Rate: Slower air flow rates allow for longer contact time between the VOC and the carbon, which increases adsorption efficiency.
