Activated carbon removes unwanted odors by acting as an adsorbent which will trap the odor inside the activated carbon and retain it. How to choose the right carbon?

Organic vapors are a major source of atmospheric pollution. They are directly responsible for a multitude of odors, and they can also supply to the atmosphere material that may react to form even less desirable components, such as smog. Most odour including industrial solvents, vent gases, and process fumes—can be eliminated and, in many cases, recovered for sale or reuse by adsorption in activated charcoal.

How to choose the right activated carbon for odor removal?

Activated carbon removes organic compounds from liquids and gases by a process known as “adsorption.” The two common materials utilized in the production of Activated Carbon are bituminous coal and coconut shell.

Coconut carbon has a micropore diameter, meaning its pore diameter is less than 2nm. Coconut activated carbon is the best for capturing molecules and holding them firmly without allowing them to escape. Coal carbon has meso pore diameter, implying their pore diameter is between 2 to 50nm, and therefore, coal based activated carbon is best for absorbing vapors of low molecular liquids.

Derun Carbon offers many varieties of activated carbon made of both materials in granular and pelletized form.

Below are the types of activated carbon we often provide to our customers.

  • KOH Impregnated activated carbon

  • Coal based activated carbon pelletized 4mm

  • 4*8mesh coconut shell activated carbon

  • H2S catalytic activated carbon for odor control

  • Spherical Potassium Permanganate Impregnated Media

How does it work to control odor?

Activated carbon has micro or macropores that attract molecules and absorbs them. When the carbon becomes activated, it creates pores of different sizes on the surface of the carbon. These pores give a path to water or air to enter the internal surface which then traps the molecules of water or air. For this purpose, virgin activated carbon is an effective solution for removing harmful odors from the environment.

What is activated carbon for Odor Control?

There are several applications that could utilize activated carbon to remove an odor. These applications include:

  • Municipal and industrial odor control

  • Refinery and chemical plant wastewater

  • Solid Waste Treatment Facilities

  • Control color and impurities in natural gas liquids (NGLs)

  • Wastewater and product storage tank vents

  • Automotive for carbon canisters

  • ACI systems for mercury reduction

  • Paint Shops

  • Pulp and Paper Mills

  • HVAC and Ventilation Systems

  • Cigarettes and Cigars Lounges

  • Volatile Organic Compounds or VOCs
