Supersonic ejectors capturing low-pressure leakage gas from the compressors gas seal vents and re-injecting it into the fuel gas line of the gas generator allow not only saving the gas that otherwise would be leaking to the atmosphere but also eliminate hydrocarbon emissions. There are also operational and maintenance benefits, as the supersonic ejector itself does not have moving parts and is inherently maintenance free. A prototype design was developed and tested at a pipeline compressor station. A family of three ejectors was designed to cover a range of operating conditions associated with gas turbine driven compressors in pipeline applications. These ejectors were built, installed on the specially designed panel and tested at the Dresser-Rand facility. A comparison of predicted and as-tested operating maps is discussed and conclusions are made about operating range.
