Efficiency And Operating Characteristics Of Centrifugal And Reciprocating Compressors

Reciprocating compressors and centrifugal compressors have different operating characteristics and use different efficiency definitions. This article provides guidelines for an equitable comparison, resulting in a universal efficiency definition for both types of machines. The comparison is based on the requirements in which a user is ultimately interested. Further, the impact of actual pipeline operating conditions and the impact on efficiency at different load levels is evaluated.
