A NEW PISTON ROD SEALING TECHNOLOGY BASED ON A PRESSURISED OIL BARRIER CAN ELIMINATE A SIGNIFICANT SOURCE OF GAS LEAKS FROM RECIPROCATING COMPRESSORS

Reciprocating compressors keep shale gas flowing. These workhorses are found throughout the industry: at wellheads, gathering stations and gas treatment plants, and along pipelines. Their ability to be driven directly from engines fuelled by natural gas makes them especially valuable in remote locations beyond the reach of grid power. Today’s recips are durable, versatile, energy efficient and cost effective, especially where high pressures are needed. Taking advantage of modern materials, computer models, manufacturing techniques and control systems, they are fully competitive with turbocompressors in many applications. Each piston rod in a doubleacting compressor requires a seal or ‘packing’ to contain the high-pressure gas on the crankcase side of the cylinder (see Figure 1). Modern rod packings are effective and long lasting, but there is always a degree of gas leakage. Leaks cost money, through the value of the lost gas and the nitrogen purge that is sometimes required to ensure safe operation.
