Centrifugal Compressors for CPI Plants
Follow this guidance to improve selection, performance and reliability of centrifugal compressors
Amin Almasi Rotating Machine Consultant
The growth in use of centrifugal compressors in chemical process industries (CPI) applications in recent decades has been brought about by four factors: 1) advances in dry gas seal technology; 2) modern aerodynamic, rotor-dynamic and thermodynamic knowledge and techniques; 3) advanced manufacturing methods to producing accurate rotating parts and various complex components with reasonable costs; and 4) the ability to simplify the control and anti-surge systems of a centrifugal compressor (and its driver) through the use of modern control and variable-speed technologies.
With these advances, and because of their simplicity, reliability, light-weight, and compact design, centrifugal compressors have become...
