Universal Efficiency Definition for Reciprocating & Centrifugal Compressors
Reciprocating compressors and centrifugal compressors use different definitions of compressor efficiency. This paper will provide guidelines for a true comparison (including valve losses, pulsation dampener losses, losses due to pulsation, station accessory losses), as well as a universal efficiency definition for both types of machines based on the requirements the ultimate user is really interested in.Further, the impact of actual pipeline conditions on the change of efficiency at different loads, using different means of control, is evaluated. Test data for either type of compressor is provided.
