Title: |
Replace Gas Starters With Air. |
Text: |
Table 1â€"Cost-Effective Options for Reducing Methane Emissions: "Replace Gas Starters With Air. Engines for compressors, generators, and pumps are often started using small gas-expansion turbines. Pressurized gas expanded across the starter turbine rotates the engine for startup, and then vents to the atmosphere. Replacing the natural gas with compressed air will eliminate this source of methane emissions. A stationary or mobile air compressor is required. Other implementation costs include installation of piping between an existing air compressor and the starter motor and electrical power for the compressor. Methane emission reductions depend on the number of engine startups and the volume of gas needed to start the motor. One partner reported total methane savings of 500 Mcf/yr for multiple engine startups." [see Table 2 and 3 in source document for costs, benefits and production characteristics] |
