PR283-22205-R01 Field Validation of a Total Emissions Efficiency Factor

Continued interest in emissions factors and operational optimization have led to a combined fac-tor, called the Total Emissions Efficiency (TEE) Score. The TEE Score considers dry low emis-sions operation, power to fuel relationships and compressor recycle, distilled into a single Key Performance Indicator (KPI). The TEE score can be used along a pipeline to help gas control and gas planning groups identify non-efficient emissions operation of a unit or station.

This PRCI study has deployed the TEE Score to a section of Kinder Morgan’s Natural Gas pipe-line and created a visual dashboard for their Gas Control utilizing Solar Turbines’ InSight Plat-form technology. The study lasted one year where Gas Control observed and interacted with TEE Scores based on Gas Control’s decisions along the selected pipeline.

One of the use cases discussed in this report is how the TEE Score can be used to self-identify units at a compressor station that could be shut down, leading to large reductions in emissions as well as savings of operational hours.

The study synthesizes real time sensor data sampled every 10 minutes for multiple compresssor stations as well as survey data from Gas Control operators and managers. This report details best practices for deployment of the TEE Score and draws conclusions about the TEE Score’s efficacy as an emissions reduction tool.
