Natural Gas Boosting

Natural Gas boosting applications have changed very little over the last several decades. What have changed are the requirements for an oil-free compressor that can minimize Volatile Organic Compounds (VOCs) and fugitive emissions and provide long term reliability. Stricter environmental regulations as well as on-site regulations have increased the demand for better technology.

The sealing technology unitized in today’s process gas compressors provides the answer: Oil-free operation preventing gas contamination as well as multiple configurations to reduce or eliminate fugitive emissions and VOCs. When properly sized and configured, the rod seals – or “packing” – use differential pressure along with a spring assist to provide a dynamic seal on the piston rod. In typical double seal machines, the lower packing (vertical machines) acts as an oil wiper preventing oil migration into the gas stream. The upper packing serves to prevent process gas from entering the crankcase, contaminating the oil sump and ultimately venting to the atmosphere. For flammable and toxic gas applications, a third packing can be utilized along with a closed loop purge system to eliminate emissions completely.

Reciprocating gas compressors have been in use for decades and have a proven track record for reliability in the field. They are oil-free, provide zero emission options and do not require any additional downstream filtration or separators. All of this equates to a lower overall cost of operation and reduced footprint in many cases.
