GE Oil & Gas develops emission-reducing technology
Posted: 12 February 2008
GE Oil & Gas today reported that its DLN-1 IBH emissions technology, which enables Frame 5-2 gas turbines running at partial load to meet new NOx emission standards, has been certified as a GE ecomagination service offering.
The DLN-1 IBH upgrade kit for the Frame 5-2 recently completed a rigorous environmental and operational evaluation to meet the requirements of ecomagination, which is GE’s commitment to address the need for cleaner, more efficient sources of energy and reduced emissions.
"Developing technologies to help customers meet their environmental challenges is a central focus of our business," said Jeff Nagel, Vice President Global Services for GE Oil & Gas.
"We foresee that within the next 3-5 years, emission regulations similar to those already in place in the U.S. and the E.U. will be applied in the Middle East and North Africa, where much of our Frame 5-2 fleet is installed. A GE DLN-1 IBH upgrade for Frame 5-2 gas turbines will allow operators to meet NOx emission standards of 42 ppm without purchasing a new turbine."
The GE Oil & Gas DLN-1 IBH technology enables a Frame 5-2 gas turbine to operate at 50 per cent rather than 80 per cent partial load, saving approximately 27 million pounds of natural gas, or approximately the amount used by more than 8,500 typical U.S. households in a year.
Installed on a Frame 5-2 gas turbine running at 50 per cent load, the new technology also lowers emissions from 80 to 42 ppm, which translates to 570 tons per year on a turbine running full time – the equivalent of taking more than 30,000 U.S. cars off the road each year.
GE's Frame 5-2 gas turbines typically are used for mechanical drive applications in the oil and gas industry. These heavy-duty machines are designed for direct coupling with centrifugal compressors over a wide operating range, including variable loads and extreme environmental conditions.
GE's DLN (Dry Low NOx) combustion system combines hardware solutions for fuel and air stream regulation with closed-loop monitoring and controls to fine tune emissions throughout the combustion process.
Since its introduction in 1980, the technology has continued to evolve and has been proven in millions of hours of operation on a wide variety of gas turbines worldwide.
The DLN-1 IBH is the fifth GE Oil & Gas product to receive ecomagination certification, joining the recently certified integrated motor compressor (ICL) designed to help compression plant operators meet their growing operational and environmental challenges.
