First dry low-emissions engine enters service

Rolls-Royce Industrial & Marine Gas Turbines? industrial RB211 is the world?s first aero derivative dry low-emissions engine to enter service. The engine entered operation at Pacific Gas Transmission Co.?s (PGT) natural gas pumping station near Spokane, Wash.

The RB211 engine is incorporated into a Coberra 6000 gas compression installation, the first of four to be supplied to PGT through Cooper Rolls Inc. Validation testing of the dry low-emissions system by Rolls-Royce has demonstrated that the NOx level in the exhaust gas has been reduced to less than 25 ppm with CO2 barely measurable.
