摘要： 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 NOx. 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.

摘要： In one aspect, the invention provides an article consisting essentially of a paper layer including about 10 Wt % to about 40 Wt % of a thermoplastic polymer and an ePTFE membrane laminated to the paper layer. Preferably, the paper layer includes about 10 Wt % to about 30 Wt % of a thermoplastic polymer. More preferably, the paper layer includes about 18 Wt % to about 25 Wt % of a thermoplastic polymer. A paper layer including about 20 Wt % of a thermoplastic polymer is most preferred. In another aspect, the thermoplastic polymer may comprise poly vinyl acetate. In yet another aspect, the invention provides a filter media consisting essentially of a cellulose paper layer including about 20 Wt % poly vinyl acetate binder; and an ePTFE membrane laminated to said cellulose paper layer. In still another aspect, the invention provides a paper layer in which the paper is cellulose paper. In yet another aspect, the invention provides a method of making a filter media consisting essentially of: providing a cellulose paper layer including about 20 Wt % of poly vinyl acetate, providing an ePTFE membrane to at least one surface of the cellulose paper layer; and laminating the ePTFE membrane to the cellulose paper layer.
