Filter System for Incineration
Since 1995, Gore has performed more than 200 polychlorinated dibenzo-dioxin/furan (PCDD/F) measurements in combustion facilities around the world. In addition, more than 700 REMEDIA® Catalytic Filter samples have been tested in more than 70 facilities, including municipal waste incinerators, crematoriums, pyrometallurgical plants, and cement kilns burning hazardous waste.
In a variety of full scale installations, the REMEDIA® Catalytic Filter System yielded dioxin emissions at levels from .012 to .065 ng (TEQ)/Nm3 - well below the standard guideline of 0.1 ng (TEQ)/Nm3. Furthermore, analysis revealed that the concentrations of dioxin in the fly ash using the REMEDIA® Catalytic Filter System were significantly lower than those achievable using a powder activated carbon (PAC) system.
The results are impressive.
Total dioxin and furan emissions to the environment - including release of both gas and solids from the baghouse - were reduced more than 90% compared to PAC systems.
These results are consistent with numerous tests performed in both full-scale systems and pilot test programs. Tests were conducted at temperatures ranging from 180° to 260°C and at filtration velocities varying from 0.8 m/minute to 1.4 m/minute. Within these ranges, the REMEDIA® Catalytic Filter System is designed to perform with the same efficiency and reduce emissions of dioxins/furans to below 0.1 ng (TEQ)/Nm3.
At facilities operating under good combustion practices - a typical inlet dioxin concentration below 10 ng (TEQ)/Nm3 - the GORE® REMEDIA® Catalytic Filter System is designed to meet and exceed dioxin regulations.
