The general trend today in compressor design is toward minimizing capital investment through greater gas flows and smaller frame sizes. Typical impeller design stresses as a consequence of this are in the range of 50,000 to 55,000 psi. With these design stresses, the stress at the overspeed test of impellers is at the 80,000 psi level. When compressor impellers are fabricated for use in hydrogen sulfide containing gases, an 80,000-90,000 psi yield strength limitation is frequently employed. This would indicate that there is little, if any, room for increases in the design capability of centrifugal compressors.
