Projections for natural gas generation growth are based mainly on the expectation of coal-fired power plant retirements, says a report titled, 'Gas and Electric Infrastructure Interdependency Analysis,' by the Midwest Independent Transmission System Operator (MISO). Taking advantage of the surplus of natural gas supply, LNG export facilities such as the nine U.S. export projects in operation or underway, offer the potential for a new baseload export market for natural gas. Canadian developers also have proposed several new export projects, the report says.
The Siemens-Masdar project assessed the CO2 purification requirements for CO2 pipeline transportation.
Siemens recently announced programs for a massive expansion of its manufacture of gas turbines and compressors in the Middle East. With its local partner E.A. Juffail & Brothers, Siemens has planned a multi-million-dollar gas turbine and compressor manufacturing facility in Saudi Arabia.
The system produces substantially pure CO2 at pipeline pressure for sequestration.
A power generation system has been proposed by British researcher Rodney Allam that claims to efficiently sequester CO2 and separate other pollutants. Termed as NET Power, the technology is capable of utilizing natural gas, coal, or biomass and does not need water to operate.
Kawasaki Heavy Industries (KHI) introduced its first industrial gas turbine in 1974 for stand-by use sets, followed by a baseload gas turbine in 1984. Since then, the company has delivered more than 10,000 GTs in the 0.2 to 18 MW range.
The annual Western Turbine Users Inc. (WTUI) conference took place this March in Pasadena, California. About 900 participants were present, and most of them were users of GE LM2500, LM500, LM6000 and LMS100 aeroderivative gas turbines. Jon Kimble, President of WTUI began the proceedings by listing the number of technical information letters (TILs) and service bulletins since last year’s event – dozens for the LM6000 alone. He said, “We provide a unique feedback loop between users and the OEM.”
Optimum gas turbine selection can be done after good comparison of the different types of turbines There are variations between aero-derivative and heavy frame industrial gas turbines including weight, size, efficiency, design, bearing type, and lubrication oil system.
In 2001, David Gordon Wilson and MIT colleagues formed Wilson TurboPower Inc. to exploit a couple of patents that Wilson had assigned to MIT. They were for low-pressure-ratio highly regenerated engines that would give around 55% shaft efficiency for 300-KW sizes. WTPI demonstrated the regenerator (it operated at very high effectiveness, over 97%) and a ceramic axial-turbine blisk made by Saint Gobain to its design that could handle the specified 1500 K TIT. However, the regenerator leaked more than it should. The patents have expired, and WTPI as such no longer exists.
This is the first of a multi-part series that focuses on how the various thermodynamic power cycles can be better integrated, combined and interlocked to give us a new overall improved system of better and more efficient energy use. The cycles working in harmony and linked together can change the way we use energy – electric power, automobiles, transportation, and freight devices.
Dresser-Rand Group Inc., a global supplier of rotating equipment and aftermarket parts and services, has recently signed a definitive agreement to acquire Synchrony, Inc. The transaction is expected to close in January 2012.
Siemens recently launched its Charlotte Energy Hub Expansion Project in North Carolina by adding gas turbine (GT) manufacturing capabilities at this site. With this, Siemens now has one centralized facility for the manufacture of gas turbines, steam turbines, compressors, electric generation equipment and servicing of the fleet.
MAN Diesel & Turbo is set to launch prototypes of the new gas turbine family into the market, shortly after the development completion. MAN is installing a CHP cogeneration unit at the Rheinberg production plant of Solvin GmbH & Co KG, a joint enterprise of Solvay and BASF. The first of MAN's new 6 MW gas turbines will be used commercially for the plant.
The capacity of centrifugal fans, their availability, investment and maintenance cost can have a significant impact on plant profitability. The plants using these fans have high technical demands and require elaborate engineering inputs.
Ventilatorenfabrik Oelde GmbH responds to these high demands with a so-called tandem drive, while ensuring compliance with various implementation rules of the API (American Petroleum Institute) and additional customer requirements, if any.
The Tandem Drive
Rolls-Royce aims to be one of the leading OEMs in a market where there is potential to generate more than 20GW of electricity worldwide. There is currently no commercial tidal stream energy industry and how it evolves and develops will depend on the actions of technology leaders and governments.
Performance testing of the 5 MW gas turbine being developed by Doosan
The DGT-5 is a 5 MW gas turbine being developed by Doosan. Below are excerpts from a paper presented by Sooyung Kim and Reewok Ryu of Doosan at the ASME/IGTI show in 2011 in Vancouver.
Centrifugal compressors are finding greater usage in Oil and Gas (O&G) applications. Particularly as less traditional forms of gas become more commonplace, they are tending to displace other types of compressors.
“Centrifugal turbocompressors more and more replace screw and/or reciprocating compressors in unconventional gas,” said Ralf Kannefass, Head of Compression & Solutions Turbo Equipment at Siemens. “This can be seen in coal seam gas or shale gas in countries with large coal and gas reserves like Australia.”
The latest LM6000 from GE has been released and is being showcased as the aeroderivative element of its recently released FlexEfficiency program. GE unveiled the machine at its Aero plant in Houston, Texas, during the week of the Turbomachinery Symposium.
Known as the GE FlexAero 6000-PH, it is a 50 MW gas turbine with a new Dry Low Emission (DLE) combustor known as DLE 2.0 which allows the unit to meet low emissions standards without the need for water.
Southwest Research Institute (SwRI) has received a $9.9 million award from the U.S. Department of Energy for Phase 3 work of a CO2 compression project. This phase is to design and test carbon dioxide compression using technologies developed under previous DOE phases of the improved compression technologies program.
The U.S. Intersolar show took place in July in San Francisco with over 22,000 attendees and 800 exhibitors. Initial keynotes dwelled upon what it will take in terms of policy and infrastructure to create a 10 GW annual market in the U.S., solar expansion (growing 67% in 2010 and demand for photo-voltaics in Q1 2011 up 66% over Q1 2010), The U.S. Department of Energy’s (DOE) SunShot Initiative which targets 50 cents per watt module manufacturing costs, and the success of the California Solar Initiative (CSI) (19,877 PV systems installed in 2010 amounting to 194 MW).
