Cat updates G3600 engine for gas compression

Caterpillar Oil & Gas said the new Cat G3600 Gen 2 Engine provides a 10% increase in power and lower emissions compared to the previous model.

The engine is the latest evolution of the G3600 series, which has more than 8,500 units in the field, the company said.

Running at full load, the Cat G3600 Gen 2 provides 33% lower methane on g/bhp basis and 6% greenhouse gas (GHG) reduction while achieving a 9.6% higher flow rate as compared to the previous model with an appropriate compressor match, the company said. Its ability to operate at lower exhaust gas temperatures affords operators a wider fuel quality tolerance, greater longevity, increased higher brake-specific fuel efficiency and reduced detonation, Caterpillar Oil & Gas said.

“With the Cat G3600 Gen 2, midstream gas compression companies can move more gas with fewer engines,” stated Matt O’Sullivan Caterpillar Oil & Gas general manager. “Companies are enabled to achieve their operational priorities while maintaining performance and efficiency.”

Additionally, the Cat G3600 Gen 2 engine has demonstrated improved durability in the field and is designed for up to 100,000 hours of operation before requiring a rebuild, with recommended maintenance. Reliable aftermarket support and parts availability combined with the engine’s long life reduces operators’ total cost of ownership (TCO).

The Gen 2 engine comes in four models: 6-, 8-, 12- and 16-cylinders.
