Cook Compression Introduces COOK CLEAN Sealing System to Lower Fugitive Emissions in Reciprocating Compressors and Support Customers’ Decarbonization Goals

DOWNERS GROVE, Ill., Oct. 17, 2022 – Cook Compression, part of Dover Precision Components and Dover (NYSE: DOV), today introduced the COOK CLEAN sealing system, a next-generation sealing system that helps lower fugitive methane emissions from packing cases to near zero levels. The COOK CLEAN product portfolio is designed to help reciprocating compressor owners and operators meet emission regulations, maximize natural gas recovery, increase compressor efficiency and reduce downtime and maintenance costs.

Reciprocating compressors are a significant contributor of continuous emissions, with leaks commonly originating from the packing case. Compressor data taken from both controlled R&D environments and machines in the field show that COOK CLEAN sealing system has documented leakage rates below 0.75 SCFM (standard cubic feet per minute) per throw.

Components of the COOK CLEAN sealing system include the following advanced technologies:

Low-emission, solid ring solutions that help eliminate leak paths.

  • Advanced technologies for purge and vent seals that create a virtually leak-proof environment, reduce frictional heat and extend the service life of the seal rings and packing case.
  • Ultra-smooth packing cup surfaces and spiral wound gasket for a superior seal.

Juan Moreno, Product Manager at Cook Compression, said, “Our portfolio of COOK CLEAN products and technology help our customers meet ambitious decarbonization goals by helping to reduce methane emissions, transition to hydrogen fuel, and optimize equipment performance to save energy. Cook Compression is a solution provider along the value chain.”
