Improved Performance of a Pipeline Compressor Station
Many pipeline owners have a keen interest in improving the efficiency of their existing compressor stations. Even small improvements in compressor efficiency can result in significant reductions in fuel costs and increases in throughput generating higher revenue. A business case for removing bottlenecks within the station piping system can be made. This paper identifies ways to evaluate a compressor stations piping system and to quantify the financial returns for improving the system efficiency. The investigation includes evaluating the system over a wide range of operating conditions required at this facility and assessing the most beneficial technical and economic solutions. The analysis is conducted with a combination of field analysis and computer simulation for an existing Piedmont Natural Gas facility.
