Gore Enterprise Holdings, Inc. - Newark DE

International Classification:

B01J 20/22

US Classification:

502401

Abstract:

The present invention is an improved filtration system, filtering method and unique chemical composition for capturing mercury and other pollutants in flue gases generated by process gas streams. The improved filtration system may take various forms depending on the type of filter system most desired for a particular application; however, the filter system includes at least a filter element or elements and an adsorbent component having a composition suitable for capturing mercury on the downstream side of the filter element.

International Classification:

B01D 46/02

US Classification:

96134, 96135, 96138, 96154, 55334, 55492

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.

Gore Enterprise Holdings, Inc. - Newark DE

International Classification:

B01D 50/00

US Classification:

55486, 55497, 55521, 55522, 55524

Abstract:

The invention provides a multiple layer filter media for removal of particles from a fluid stream. The multiple layer filter media may include a depth filtration layer, a membrane filtration layer and a support layer. Additional layers may be present. The membrane filtration layer may comprise expanded polytetrafluoroethylene (ePTFE). The various layers of the multiple layer filter media may be bonded together through a plurality of point bonds. The point bonding process may include simultaneously bonding multiple layers of the multiple layer filter media together in a single operation. The point bonds may be created using ultrasonic bonding.
