Compressor Selection Maps
Compressor selection maps per API 617/618/619 — operating envelopes, polytropic efficiency ranges, specific power, surge and turndown limits, molecular weight suitability, discharge temperature limits, capacity control methods, pulsation requirements, lubrication/maintenance intervals, and selection criteria for centrifugal, reciprocating, screw, scroll, diaphragm, and axial compressors
