Vapor Treatment

VAPOR PHASE CARBON Granulated ACTIVATED CARBON The Facts

PRINCIPAL Granulated Activated Carbon(GAC) is a porous sponge-like substance. Carbon technologies are used to treat contaminated liquid and vapor streams. The technology involves passing these fluids through a media bed with a large surface area. The large surface area on the carbon is where the chemical compounds are held. Activated carbon has more surface area per gram than other materials. The surface area ranges from 500-2000 m2/g. Because of the diversity in porous area, carbon has a wide range of contaminants that it can treat. The adsorption potential of contaminants to the carbon surface is controlled by van der Waals forces, that is the weak attractive forces between molecules. GACs adsorbs organic material due to the attractive forces between the GAC surface(non-polar) and the contaminant(non polar) are stronger then the forces keeping them dissolved in water or diffused in vapor.
GRANULATED CARBON ACTIVATION Most Carbon is activated using steam. Activation is also accomplished using chemicals. Wood based carbons steam activation involves a two step process, carbonization and activation. Carbonization occurs in an oxygen deficient environment at high temperatures, 700 degree Celsius. Activation of carbon occurs by using steam where temperature of the carbon is raised to 1800 degrees. During the steam process, some of the atoms are volatilized leaving a highly porous media. During the steam process, some of the atoms are volatilized leaving a highly porous media.
Key factors in affecting Carbon Absorption Performance Several parameters can effect influence carbon absorption performance and should be evaluated as part of the design process. They include the competitive absorptive nature of different compounds, temperature, pH and solubility. Competitive Adsorptive: Strong carbon bound organics can actually push off weaker organics. This process is referred to as the “roll off phenomena”. The organic compound is often found in the effluent as breakthrough driving carbon consumption up. Software programs are used to estimate carbon loading equilibrium with several different compounds and predict carbon usage. Temperature: In vapor phase carbon the ability for carbon is diminished by as much as 20% at 90°F and stops adsorbing and starts to desorbing at 125°F. Contact Time:. The greater the retention time the greater the absorption

Thermal\Catalytic Oxidation
Thermal\Catalytic Oxidation is a system use the heat of the oxidation process to burn vacuum -extracted hydrocarbon vapor from contaminated soil or from air stripper off gases and destroy them by using a thermal or catalytic oxidation process.. Pollutants such as Volatile Organic Compounds (VOCs), Hazardous Air Pollutants (HAP’s) and odors are oxidized to carbon dioxide and water. Our OE Therm/Cat unit operates using several types of burners depending on the process stream. High VOC Destruction levels, greater then 99.99, can be achieved with the OE burner. The OE Therm/Cat is compact and can easily be installed be installed at contaminated soil site. When haloginated compounds are treated a scrubber and neutralization system is added.
