Activated carbon for biogas with lower wear on the plant
Documented cleaning for operation with fewer interruptions
Are you using activated carbon for biogas, where the gas stream needs to be cleaned before it hits the engine, filters or other sensitive equipment? Activated carbon for biogas becomes relevant when unwanted gases, odors, VOCs or siloxanes can wear down the plant and result in shorter operating intervals. At Dankalk K/S, we as a limeworks help companies with activated carbon for air purification and gas purification, where the type of carbon, load and replacement must suit the specific operation.
In biogas plants, incorrect carbon selection can lead to faster saturation, poorer cleaning and more interruptions. The wrong activated carbon for biogas can lead to rapid saturation, poorer removal of VOCs and siloxanes, and more wear on the motor, filters and gas equipment. Therefore, activated carbon must be selected according to the gas stream content, moisture and expected load.
5 advantages of our activated carbon for biogas
Activated carbon for biogas must be able to handle the gas flow that the plant actually produces. Therefore, the choice is not only about price per unit, but also about capacity, lifespan and how well the carbon protects the rest of the plant.
- Special types of activated carbon for gas and air purification
- Advice on coal type based on load, humidity and operating time
- Products for removing VOCs, siloxanes and odors
- Focus on lower wear on motors, filters and process equipment
- Deliveries to plants where stable operation requires correct cleaning
When activated carbon matches the humidity, concentration and load of the gas stream, the capacity of the carbon is better utilized, and there is a better basis for stable purification and longer intervals between replacements.
This reduces the risk of premature saturation and provides a better correlation between carbon consumption, replacement interval and the substances contained in the gas stream.

Activated carbon protects engine and gas equipment
Activated carbon is used in biogas because the gas stream can contain compounds that wear out engines, filters and technical components. The carbon acts as an adsorbent material, binding unwanted substances into the carbon’s porous structure before the gas is used further.
This cleaning is especially important before engines and energy production, where impurities can cause deposits, corrosion or poorer operation. A correctly selected carbon filter can therefore be the difference between planned service and expensive shutdowns. It provides better protection before engines, filters and gas equipment, where VOCs, siloxanes and other impurities can otherwise affect operating time and maintenance.
Carbon type, load and replacement must match
Different types of activated carbon react differently to humidity, concentration and operating conditions. Therefore, the product should be selected according to the actual gas flow and not just based on a standard solution. Granular carbon, flaked carbon and pellets can have different advantages depending on the task.
For industrial gas and air streams, the Alcarbon series can be used where VOC reduction is important. For sulfur-containing gas streams, Desorex G50 is used as pellets with high capacity and stable function in gas purification plants, while ferric chloride can be relevant in wastewater where hydrogen sulfide needs to be bound earlier in the process. This provides a more precise choice when the purification requirement is known in advance.
Activated carbon for gas streams with moisture, VOCs and siloxanes
Activated carbon for air purification should be selected based on the humidity of the gas stream, contact time, concentration of VOCs and risk of siloxanes in the equipment. Too high humidity, incorrect contact time or too low capacity can make the purification less stable and shorten the life of the carbon.
When choosing activated carbon, you should look at what substances need to be removed, how high the load is, and how long the carbon needs to function between replacements. In biogas, it is especially moisture, VOCs, siloxanes, and contact time that determine whether the carbon effectively protects the engine and gas equipment.
These three factors affect operation, cost and maintenance. When the carbon type matches the load, it becomes easier to plan replacement, avoid wasted capacity and protect engines, filters and gas equipment.
Activated carbon for air purification in technical systems
Activated carbon for air purification is not only used in biogas. It is also used in industrial processes and ventilation air, where odors, VOCs and organic compounds need to be reduced. Common to the tasks is that the structure and capacity of the carbon must match the flow passing through the filter.
An air purification solution with activated carbon can be used as primary purification or as polishing after other purification steps. In plants where both gas, sludge and process water must be controlled, polymer can also be relevant for separation and sludge dewatering, while activated carbon handles odorants, VOCs and siloxanes in the gas or air stream. The specific solution depends on the load in the plant and the desired operating time.
