Case Studies

Petrochemical plant

Upgrade Doubles Packing Case Life in Dirty Gas

With packing case sealing components on a non-lubricated compressor wearing out at intervals of less than four months, a petrochemical plant sought an upgrade to reduce product leakage and equipment downtime.

Cook Compression applied low-leakage packing ring designs with proprietary TruTech™ materials on all three stages, more than doubling the mean time between maintenance and creating significant savings.

Packing case upgrade to address vent leakage

Upgrade Extends Service Life, Reduces Vent Leakage

Operators at an aromatics plant were searching for ways to increase rod packing life and reduce seal leakage on a lubricated compressor in hydrogen service.

After a field inspection, Cook Compression proposed a comprehensive packing upgrade that included cooled packing cases with advanced pressure breakers, low-leak seal rings and low-friction vent seal technology. The upgrade achieved more than 18 months of continuous run time and gas vent leakage near zero scfm.
