20070095203 - Method to remove an agent using a magnetic carrier from the gaseous phase of a process: The subject of the invention is a process for removal or separation of agents from dynamic process systems, particularly when the agent may be hazardous. Its primary embodiment lies in the removal of mercury from the exhaust from fossil fired heating systems, however, it can be seen as also applicable... Agent: Butler, Snow, O'mara, Stevens & Cannada PLLC

20070095204 - Axial transfer line degassing: An elongated flow-through degassing apparatus includes an elongated gas and liquid impermeable outer member and a gas-permeable, liquid-impermeable inner barrier extending within the outer member and at least partially along a first chamber defined within the outer member. The apparatus also includes inlet and outlet connection structures operably coupled to... Agent: Mark J. Burns Haugen Law Firm Pllp

20070095205 - Method for processing landfill and other stranded gas containing commercial quantities of methane and contaminated by carbon dioxide, nitrogen and oxygen into a pipeline or vehicle quality natural gas product: Stranded natural gas, when contaminated by difficult to remove constituents such as Nitrogen and Oxygen, has long been considered uneconomical to process into pipeline quality gas and is abandoned or utilized in other energy applications where economically viable. Landfill Gas (LFG) is often considered a stranded gas although in many... Agent: Peter F Weinberg Gibson Dunn And Crutcher LLP

20070095206 - Fuel deoxygenation system with multi-layer oxygen permeable membrane: A fuel system for an energy conversion device includes a deoxygenator system with an oxygen permeable membrane formed from a multiple of layers.
