Seneca Resources Company, the exploration and production segment of National Fuel Gas Company (NFG), and NexTier Oilfield Solutions (NEX) announced their intent to pioneer an innovative study evaluating the carbon [...]

The constantly evolving energy market is forcing gas turbine power plants to operate in new and demanding ways. The combined impart of intermittent renewables and tightening emissions requirements is compelling [...]

A supersonic ejector used on a 24-megawatt compressor-gas turbine unit saved as much as 99,000 watts and reduced carbon dioxide emissions by as much as 1,656 tonnes a year. The optimal design of the supersonic ejector gave an expansion pressure ratio of 14.0 and a compression pressure ratio of 8.1.

The Vision 21 program initiated by the US Dept of Energy is primarily aimed at improving the efficiency of power production in the country while reducing the adverse environmental impact of fuel-flexible generation facilities. Cited by government officials as a means of developing industrial research in the new millenium, the Vision 21 initiative is based on the 192 Advanced Turbine Systems program which seeks to help companies acquire 60% efficiency in utility scale systems and reduce the cost of electrical consumption by as much as 10%., The US Department of Energy's Vision 21 looks to the future of the power industry, with a number of very ambitious objectives, building on the ATS Programme, which is nearing [...]

While specifically designed for gas turbines, Concat™ GT compact extruded ceramic SCR catalyst is suitable for use in new or retrofit applications. It provides honeycomb structure that results in up [...]

The chemical reaction that produces thermal [NO.sub.x] during combustion occurs at temperatures greater than approximately 2,800 F, and the rate of [NO.sub.x] production accelerates exponentially with increasing temperature New gas-turbine [...]

In today's competitive power markets, equipment manufacturers must have products that not only meet regulatory requirements, but also meet users' needs in terms of cost, reliability, maintainability and more. The [...]

In an April 14, 2003 direct final rule (68 FR 17990-18002), EPA revised the new source performance standards (NSPS) for stationary gas turbines to codify several alternative testing and monitoring [...]

Investment casters supplying parts for engines for aerospace, automotive, and industrial power generation lately have a new operating challenge: many of these foundries use refractory ceramic fiber (RCF) as thermal [...]

Environment directorate DGXI is making little progress with plans to draw up legislation to deal with the problem of polluting emissions from gas turbines. Work is now not likely to restart on this issue until late 1994, and the final structure of the Commission's draft directive will not be known until then. It is hoped to mirror US legislation on gas turbine emissions, setting a single emission standard for the whole of the European Community.

Eemscentrale gas turbine emits only 9ppm [NO.sub.x] In 1988 the existing 590 MW reheat steam boiler/turbine unit at Eemscentrale near Groningen in The Netherlands (see Figure 1) was upgraded and [...]

GE Oil & Gas has announced that its DLN1 IBH emissions technology, which enables Frame 5-2 gas turbines running at partial load to meet new NOx emission standards, has been [...]

'As in the previous Kazakh projects, driving the compressor lines will be the GE Frame 5D heavy-duty gas turbines, 30-MW-class machines for high-pressure applications. In order to limit exhaust emissions, [...]

In an April 14, 2003 direct final rule (68 FR 17990), EPA revised the new source performance standards (NSPS) for stationary gas turbines to codify several alternative testing and monitoring [...]

Important advances are being made by Kvaerner in the battle to reduce carbon dioxide (C[O.sup.2]) emissions offshore. The company has developed a method for removing C[O.sup.2] from the exhaust of [...]
