Abstract
An improved filtration apparatus, filtering method and filtering material for capturing mercury and other pollutants in pollutant-laden fluid streams such as flue gases generated by process gas streams are disclosed. The improved filtration system may include two pollutant remediation layers, an upstream layer capable of filtering particulates and a downstream layer capable of adsorbing and/or catalyzing pollutants such as mercury, dioxin, furans, and NO. The improved filtration system may be in the form of a particulate filter bag. The particulate filter bag may be configured for use in a reverse air filtration system with the upstream layer facing an internal volume of the bag. The upstream layer may include an ePTFE layer laminated to the upstream side of the upstream layer.
