GE launches eco-friendly products
Dubai, February 16, 2009
More power and lower emissions are key features of three newly certified ‘ecomagination’ products from GE Oil & Gas.
These include a PGT25+ dry low emissions (DLE) aeroderivative gas turbine, designed specifically for oil and gas applications, a PGT25+G4 aeroderivative gas turbine module and the ORegen waste heat recovery system, which can produce additional power without any further emissions and no water use, according to a statement.
“Given the current global economy, the oil and gas industry is looking for proven, cost-effective solutions to optimize the performance of facilities and also demonstrate a commitment to reduce their environmental footprints,” said Claudi Santiago, president and CEO, GE Oil & Gas. “GE’s ecomagination certification is an important tool that we can use to quantify the value of our PGT25+ and PGT25+G4/DLE technologies and ORegen waste heat recovery system for our customers.”
Ecomagination is GE's corporate commitment to help customers overcome their environmental and economic challenges. To earn ecomagination certification, a product is evaluated for its ability to significantly and measurably improve the customer's environmental and operating performance.
The rigorous, multi-tiered review process is concluded with an independent, third-party audit to ensure accuracy and thorough documentation of technological performance. To date, eight GE Oil & Gas products have received ecomagination certification.
At base load conditions, GE’s PGT25+DLE and PGT25+DLE G4 aeroderivative gas turbine technology operating on natural gas has an efficiency of 41 per cent, the highest in the 30-35 megawatt power range, producing lower CO2 emissions per megawatt of power output than competing technologies.
When coupled with a simple-cycle gas turbine, the ORegen system generates electricity from waste heat while consuming no additional fuel or water and avoiding associated CO2 emissions. A simple-cycle gas turbine equipped with the ORegen system operating more than 8,500 hours a year, compared to the same turbine operating in a combined-cycle system, generates additional electricity while avoiding the consumption of more than 11,000 cubic meters of water per year ─ equivalent to more than four Olympic swimming pools, the statement said.
The ORegen system is ideal for use in locations where water is scarce or cannot be exploited. It does not require on-site manned supervision and can operate at very low ambient temperatures.
“Many industrial processes generate waste energy that passes out of plant stacks into the atmosphere and is lost. Energy recovered from waste heat streams could supply part of the electric power required by a plant, at no additional cost. Therefore, heat recovery offers a great opportunity to conserve by productively using this waste energy to reduce overall plant energy consumption and simultaneously decrease CO2 emissions,” Santiago added.
More than 80 products from across GE’s corporate portfolio have earned ecomagination certification since the program was launched in 2005. – TradeArabia News Service
