Twenty Years Of Experience With A Modular Design System For Centrifugal Process Compressors.
The design of single shaft horizontally split and barrel type compressors is based on a modular design system, which comprises fixed geometry components, i.e., impellers, diffusers, return vane channels, scrolls, and inlet ducts. The philosophy of the system is based on limited deviations from aerodynamic similarity. The performance curves of each individual fixed geometry stage were deduced from aerodynamic measurements carried out either with atmospheric air (for the low convergency line) or with freon (for the high convergency line). The aerodynamic similarity principle assures the validity of these stage measurements for the operation with all other industrial gases, whose molecular weights range from 4.0 to 120.
