Cost of high capacity compressors ($/kW)

Click For Summary
SUMMARY

The discussion focuses on the cost analysis of high-capacity compressors, specifically GE axial compressors used in petroleum and power applications. It highlights that as power capacity increases, the cost per kilowatt ($/kW) decreases, although the available online resources do not provide pricing for capacities above a few tens of kilowatts. For compressors with a capacity of 4 MW, users are advised to contact equipment vendors directly for accurate quotes, as such equipment is not typically listed in catalogs. Additionally, the conversation notes that efficiency gains are limited by thermodynamic principles.

PREREQUISITES
  • Understanding of compressor types, specifically GE axial compressors.
  • Knowledge of power capacity measurements in megawatts (MW).
  • Familiarity with cost analysis metrics, particularly $/kW.
  • Basic principles of thermodynamics related to efficiency.
NEXT STEPS
  • Research the pricing models for high-capacity compressors from various vendors.
  • Explore thermodynamic efficiency limits in large-scale compressor applications.
  • Investigate the specifications and performance metrics of GE axial compressors.
  • Learn about the procurement process for industrial equipment in petroleum and power sectors.
USEFUL FOR

Engineers, procurement specialists, and project managers involved in the selection and purchase of high-capacity compressors for industrial applications, particularly in the petroleum and power industries.

Hello -

I was looking at costs of compressors online and could find a couple of links that provided me $ for the power I was looking at. As the power increases, $/kW decreased. The range of kW that these websites could give me cost for was well below what I was looking at.
Can someone help me with the cost of a compressor with a capacity of 4 MW. The likes of GE axial compressors that are used for Petroleum or Power applications.

Thanks

Equipment of that size doesn't come with a price tag in a catalog. You'll need to speak directly to an equipment vendor and get a quote.

That said, I'd be surprised if the efficiency increases much once you get above a few tens of kW in size - the theoretical maximum efficiency is a matter of thermodynamics.
