Could a Different Seal Technology Reduce Your Energy Use, Emissions and Lifecycle Costs?

Whether you’re specifying capital projects or considering a sealing technology upgrade, it’s critical to understand the true impact of that investment. We developed this comprehensive calculator to help you identify the associated costs, energy requirements and greenhouse gas (GHG) emissions associated with five common seal technologies for a centrifugal gas compressor. 


View our calculator now to get an accurate, immediate overview of the energy, emissions and lifecycle costs of these five scenarios:

  • Traditional oil seal and seal support system, with seal leakage vented into the atmosphere
  • Traditional oil seal and seal support system, with seal leakage vented to flare
  • Traditional oil seal and support system, fitted with an enhanced leakage recovery system that captures seal leakage and redirects it to an alternative value-adding use
  • Non-contacting dry gas seal and seal support system venting into the atmosphere
  • Non-contacting dry gas seal with a seal gas recovery system that recovers seal leakage and diverts the gas stream to the compressor for more productive purposes

Use our calculator now to see how dry gas seals and gas recovery systems can support your sustainability initiatives and bottom line. Then, contact our experts to advance your sustainability progress.
