liquid-Cooled Packing Assemblies For GaS Compressors: Technology spreads as discharge pressures continue to grow

摘要

Liquid-cooled packing assemblies have been available for many years in petrochemical nonlube applications where lubrication may contaminate the product being manufactured. In this type of service, without lubrication, temperature removal from the sealing area is a major factor in maintaining acceptable packing ring life. The early installations used external cooling that circulated around the outside diameter of the packing case. As designs improved, coolant was brought closer to the heat source with internal circulation in the packing cup itself.
