| Title: |
Reduce Methane Emissions From Compressor-Rod Packing Systems. |
| Text: |
Table 1â€"Cost-Effective Options for Reducing Methane Emissions: "Reduce Methane Emissions From Compressor-Rod Packing Systems. Calculating an economic rod packing replacement threshold, and monitoring packing leakage, can save both methane emissions and maintenance costs on reciprocating compressors. Gas leaks from compressor rods represent one of the largest sources of emissions at natural gas compressor stations. All packing systems leak under normal conditions. A new packing system, properly aligned and fitted, may lose approximately 11 to 12 scf/hr. One gas producer measured emissions of 900 scf/hr on a single compressor rod. A simple calculation using company-specific financial objectives and monitoring data can determine emissions levels at which it is cost-effective to replace rings and rods."
