The Heat Exchange Institute (HEI) recently released the first edition of Standards for Air Cooled Condensers. The Standard offers technical information from the combined expertise of the members of the HEI Air Cooled Condenser Section and includes typical purchaser requirements. HEI Standards are used throughout the world for the design, manufacture, and operation of HEI scope equipment.
In addition, the standard outlines the important design criteria for air cooled condensers and provides practical information on nomenclature, dimensions, testing, and performance.
Alstom GT24 gas turbine boosts operational flexibility
November 26 2011 -
The next generation of the Alstom GT24 gas turbine has been designed to deliver over 230 MW at 40% efficiency (heat rate of 8'571 Btu/kWh). The corresponding KA24 CCPP can achieve 700 MW output in a 2-on-1 configuration and operate at greater than 60% efficiency and a heat rate of less than 5,714 Btu/KWh.
Design and operating considerations for combined cycle plants
November 26 2011 -
The prevailing economic conditions, volatility of fuel prices, changing regulation of emissions, varying supply and demand as related to capacity margins and unfavorable public perception of coal and nuclear technologies have brought uncertainty in today's energy market.
Shell Lubricants announced recently the arrival of its first shipment of gas-to-liquid (GTL) base oil at the Port of Houston. The product, the first from the Qatar-based Pearl GTL plant to reach the Americas, will be stored at a hub in Houston and routed to Shell Lubricants' GTL-enabled blending facilities throughout the United States.
Once the Pearl GTL plant starts operating at full capacity, it will be one of the world's largest sources of lubricant base oils with the capacity to produce about 30,000 barrels per day, enough to fill 225 million cars per year.
The Emir of Qatar formally inaugurated the Pearl Gas to Liquids (GTL) Project, the largest GTL plant in the world, today. The project has been jointly developed by Qatar Petroleum and Shell. Pearl GTL turns natural gas into high quality liquid fuels and products using innovative technology and engineering.
TransCanada Turbines (TCT) has opened a new 220,000 ft2 overhaul and repair facility in Airdrie, Alberta. The new facility houses production, project management and support staff for TCT’s GE Level 4 and Rolls-Royce MROC services, and replaces the old facilities in Calgary and Airdrie.
While there has been extensive discussion and analysis of the requirements for integration of renewableelectricity generators with the electric grid, there has been much less focus on the interactions with thenatural gas grid, which, nevertheless, could be significant. There is widespread agreement that gas-based generation will be an important component of renewable integration but there has been little detailed analysis to date of the potential interactions between the electric and natural gas systems.
NAES Corporation, a service provider to the energy industry, has announced that it has entered into a preferred vendor agreement with Fluitec International. NAES endeavors to form relationships with leading companies that provide value to plant owners. These relationships manifest through preferential services, scheduling priority, and cost concessions commensurate with the volume of business that a given company conducts with the NAES operated fleet.
