Emission-reducing technology for gas turbines

The GE Oil and Gas DLN-1 IBH emissions technology upgrade kit enables Frame 5-2 gas turbines running at partial load to meet new NOx emission standards (42ppm)

The DLN-1 IBH upgrade kit for the Frame 5-2 addresses 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 and Gas.

"We foresee that within the next 3-5 years, emission regulations similar to those already in place in the US and the EU 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 and Gas DLN-1 IBH technology enables a Frame 5-2 gas turbine to operate at 50% rather than 80% partial load, saving approximately 27 million pounds of natural gas, or approximately the amount used by more than 8,500 typical US households in a year.

Installed on a Frame 5-2 gas turbine running at 50% load, the new technology also lowers emissions from 80 to 42ppm, which translates to 570tons per year on a turbine running full time - the equivalent of taking more than 30,000 US cars off the road each year.

GE 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.

The GE 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 and 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.
