Natural gas oxy-fuel cycles—Part 3: Economic evaluation

Two novel oxy-fuel power cycles integrated with natural gas reforming and CO2 capture

Two novel system configurations were proposed for oxy-fuel natural gas turbine systems with integrated steam reforming and CO2 capture and separation. The steam reforming heat is obtained from the available turbine exhaust heat, and the produced syngas is used as fuel with oxygen as the oxidizer. Internal combustion is used, which allows a very high heat input temperature. Moreover, the turbine...

I Evaluation of Natural Gas as an Alternative Fuel in

The energy issue in transportation for the next 20 years is not one of adequate supply but rather it is a combination of overdependence on imported petroleum and of managing a transition to economically, strategically and environmentally desirable energy sources. More than a quarter of all energy consumption in the United States is attributable to transportation, as is nearly two-thirds of all ...

The Impact of Teaching Oxy-Fuel Welding on Gas Metal Arc Welding Skills

Industrial technology programs around the country must be sensitive to the demands of manufacturing and industry as they continue to replace “vocational” curriculum with high-tech alternatives. This article examines whether or not teaching oxyacetylene welding in the industrial technology classroom is required to learn arc welding processes. The results of this study suggests that there appears...

Energy, Greenhouse Gas, and Economic Implications of Natural Gas Trucks

Until recently, natural gas was an also-ran in the sweepstakes for changing the face of transportation in the United States, even though expanded reliance on natural gas vehicles (NGVs) holds the promise of reducing carbon emissions, reducing dependence on oil, and even lowering transportation costs. Recently, however, interest in natural gas as a transportation fuel has grown, as shale gas res...
