The following are emission levels obtained from air pollution control systems using our PUREFRAX® filter elements. In order to show the levels of air pollution abatement possible, they have been compared to the extremely stringent emission limits specified within the Waste Incineration Directive (WID) – Directive 2000/76/EC.

Example 1: Taken during emissions testing at a gasification facility processing Municipal Solid Waste (MSW). This system utilizes Sodium Bicarbonate sorbent injection.

Pollutant WID limit Emission Level Achieved – % of WID limit
Particulates 10 mg/m3 9.1%
TOC 10 mg/m3 1.6%
HCl 10 mg/m3 12.2%
CO 50 mg/m3 16.0
SO2 50 mg/m3 <1%
NOx 200 mg/m3 38.0%
HF 1 mg/m3 13.1%
Cd and Tl 0.05 mg/m3 3.2%
Hg 0.05 mg/m3 12.2%
Sb, As, Pb, Cr, Co, Cu, Mn, Ni, V 0.5 mg/m3 8.2%

 

Example 2: Taken during emissions testing at an Aluminum De-coating facility processing heavily contaminated scrap (up to 40% PVC by weight). The system uses Sodium Bicarbonate sorbent injection and operates above the de-Novo synthesis temperature window to prevent the reformation of Dioxins/Furans.

Pollutant WID limit Emission Level Achieved – % of WID limit
Particulates 10 mg/m3 3%
SO2 50 mg/m3 16%
NOx 200 mg/m3 9%
HCl 10 mg/m3 30%
Dioxins/Furans 0.1 ng/m3 14%
