Reciprocating compressors in natural gas gathering and processing must accommodate great variety in gas composition, including non-hydrocarbons such as hydrogen sulfide, carbon dioxide, and water vapor. Shale gas often contains particulates and contaminants that can shorten component life.
Add to this the use of portable compression equipment, or systems designed to be scalable as field pressure declines, and reciprocating compressors must cover a wide range of operability.
Challenges come from other areas as well, including regulatory requirements. Gas producers face national and local regulations regarding emissions and air quality, and reciprocating compressors are frequently targeted to meet reduction goals.
Cook Compression can partner with you to address these needs and other complexities unique to your application.
Depending on your emissions objectives, Cook Compression emissions solutions range from repair services to component upgrades to complete system analysis.
Our compressor repair services, including cylinder overhauls, restore components to factory specifications and clearances, providing like-new performance. We can also offer upgrades for enhanced sealing performance, whether through seal-enhancing rod coatings, advanced materials that extend the life of piston rings and riders, or COOK CLEAN™ purged packing cases to prevent fugitive emissions.
Sentrix™ thermal mass flow meters can help detect and quantify leakage and target the solution that works best for your equipment.
That’s where the Cook Compression projects group can step in, adding their expertise to your team for diagnostics, engineering studies and the creation of a tailored, system-based solution.
Along with impurities and potential debris in the gas, reciprocating compressors in natural gas gathering and processing must withstand high speeds, and valve failures are common. Cook Compression provides a range of robust, high-performing valve solutions to address this need.
The Ring Damped Valve is designed especially for high-speed compressors. This robust valve reduces impact forces and protects against impact fatigue. In addition, the design increases the flow area – significantly reducing the horsepower required to move gas.
For service in dirty natural gas, the multi-disc element MOPPET valve offers a proven, rugged construction able to extend service life, even in the presence of debris.
Reciprocating compressors in gas lift applications commonly rely on Optima Series valves, custom-engineered plate valves with a wide range of design options.
