RISWeb-Based and Geospatially Enabled Risk Screening Tool for Water and Wastewater Pipeline Infrastructure Systems
Publisher: American Society of Civil Engineers
Abstract: This paper focuses on the development of a web-based geospatial tool as a proof of concept to assist water utilities in performing a network-level risk screening of their buried water and wastewater pipeline infrastructure ...
Low Temperature Combustion Using Nitrogen Enrichment to Mitigate NOx From Large Bore Natural Gas Fueled Engines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Low temperature combustion is identified as one of the pathways to meet the mandatory ultra low NOx emissions levels set by the regulatory agencies. Exhaust gas recirculation (EGR) is a well ...
In-Cylinder Equivalence Ratio Measurements in an EGR Equipped Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A single-cylinder natural gas fueled engine equipped with an exhaust gas recirculation (EGR) system was ignited using a laser. The broadband emission from the spark kernel was spectrally resolved, ...
Air Separation Membranes: An Alternative to EGR in Large Bore Natural Gas Engines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Air separation membranes (ASMs) could potentially replace exhaust gas recirculation (EGR) technology in engines due to the proven benefits in NOx reduction but without the drawbacks of EGR. ...
