Vapor Phase, Pelletized Carbon

HS-AC-P Vapor Phase, Coal Pellet Activated Carbon

Hydrosil’s HS-AC-P-HS is highly active wood or coal based pelletized carbon. The carbon is manufactured for vapor phase applications. Hydrosil’s HS-AC-P-HS is a high-quality carbon with extraordinary surface area, fine pore structure, high density, and superior hardness. This type of carbon has an extremely high adsorption capacity for hydrogen sulfide of 0.3 g/cc.

Depending on the application Hydrosil will help you select if a wood based pelletized carbon or a coal based pelletized carbon is correct for your application. Coal based pelletized carbon is more commonly used in odor control applications where hydrogen sulfide is a concern. Wood based pelletized carbon is used for more specific applications.

The HS-AC-P-HS is used in a variety of odor control applications within the paper, food, biogas, process and wastewater treatment industries. The media can be loaded in tanks, exhaust systems, general HVAC systems, and deep bed scrubbers. HS-AC-P-HS is commonly used in sewage odor control vessels or scrubbers in lift stations to control odors such as hydrogen sulfide.
