1. A system, comprising:
- a centrifugal gas compressor, comprising;
an impeller;
a diffuser configured to convert velocity into pressure for a fluid flow from the impeller; and
a scroll configured to direct the fluid flow from the diffuser out of the centrifugal gas compressor;
wherein the diffuser comprises a plurality of diffuser vanes arranged in an asymmetrical pattern around a mounting surface of the diffuser.

Abstract
A system, in certain embodiments, includes a centrifugal compressor diffuser having a mounting surface and plurality of diffuser vanes extending from the mounting surface in an axial direction and forming an asymmetrical (e.g., non-periodic) pattern around the circumference of the diffuser. The asymmetrical pattern may be determined based upon characteristics of fluid flowing from an impeller across the diffuser and through a scroll of a centrifugal compressor.
