HP Reliability: Four-stage, low-flow process centrifugal compressor can fill important industry gaps

In the 1970s and 1980s, multistage centrifugal compressors in the 3,000 acfm (about 5,000m3/hr) and lower flow ranges were largely confined to instrument and plant air duties. Three stages with intercooling were common. Only a Colorado-based centrifugal compressor manufacturer concentrated on developing vertical single-stage machines.1 Forward-looking users applied these new single-stage machines in steam recompression and select process gas services, as shown in Fig. 1.1     Fig. 1. Inlet volumetric flow vs. pressure ratio   for single- and four-stage integrally gear-  driven compressors. Source: Sundyne LLC,   Arvada, Colorado. New compressor for
