New engine for gas compression use
GE Energy, Atlanta, has introduced the J312 GMD, its first Jenbacher gas mechanical drive engine for use in gas compression.
The new engine was installed in December 2004 at a gas-gathering field in northern Louisiana. The unit is driving a GE high-speed, Model A354 three-stage compressor and is compressing 3.5 MMcfd.
The 12-cylinder engine is rated at 676 bhp at 1,800 rpm and was engineered and tested at GE Energy’s gas engine center in Jenbach, Austria.
The initial compressor system was designed and packaged by Standard Equipment Co., Houston. Mustang Gas Co., a rental compression and service company located near Houston, placed the new engine-compressor package at a Louisiana gas-gathering facility.
GE’s Jenbacher gas engines range in output from 0.25 to 3 Mw and run on natural gas as well as various specialty gases created from biomass, landfills, coal mines, sewage, and industrial wastes.
Equipped with patented combustion systems, engine controls and monitoring technology, Jenbacher systems meet all relevant international emission standards while offering high levels of efficiency, durability, and reliability, the company says.
The J312 GMD comes with the DIA.NE XT monitoring system, which interfaces easily with compressor controls and provides an air-fuel ratio control to help maintain NOx emissions without using oxygen sensors. All engine information is available on an easy-to-use interface panel that does not require any additional devices.
