How Activated Carbon Works in a Gas Phase Filtration Process

Activated Carbon filtering is actually an adsorption process where contaminants are removed via the process of chemical adsorption and captured within the matrix of the carbon substrate.

The word adsorb is important to understand as it is a form of chemical attraction when contaminants are removed through this process. Each particle, or granule, of carbon provides a large surface area, or pore structure, allowing contaminants the maximum possible exposure to the active sites within the filter media. One gram of activated carbon has a surface area in excess of 3,000 m2 (32,000 sq. ft.).

What is Activated Carbon Used For?

Activated carbon is commonly used for liquid applications to remove dissolved organics but is also used to remove various molecular contaminants from air and gas to control emissions and ensure environmental compliance. To control odors, VOC (Volatile Organic Compounds) and H2S from Biogas, utilizing a Vapor Phase Carbon System and the correct carbon type for the application can be a viable cost effective solution. Vapor phase activated carbon adsorption medias have a high activity level in combination with a selection of transport and adsorption pores that accommodate adsorbates of varied molecular sizes.

Activated carbon media can be used for tank venting, air stripper off-gas, soil venting, and removal of vapors when soil is being remediated, and other applications where control of environmental emissions is of critical importance. Strict environmental air quality regulations dictate that companies reduce the amount of emissions they can release into the atmosphere and minimizing the release of VOC (Volatile Organic Compounds) and other vapor phase contaminants is a must for those who want to avoid penalties and fines for non-compliance.

Depending on the application, it could be as simple as an off the shelf 55 gallon drum style set-up or a complete package for high flow rates to 20,000 cfm or a system somewhere in between. Either way we can provide a cost-effective solution with a quick turnaround time to avoid regulatory compliance issues.

Systems can be purchased or rented as required to meet your specific goals and tailored for your process application. We can work with your team and ensure we are on the same page find a timely and cost-effective solution.
