Tutorial on Centrifugal Compressor Surge Control

Abstract

For every centrifugal compressor installation, the design of the surge control system is vitally important to prevent damage of the compressor internal components, seals, and bearings. While most surge control systems are capable of preventing surge for steady-state operation, emergency shutdowns (ESDs) are particularly challenging, since the surge control system must respond faster than the deceleration rate of the train. This tutorial explores various aspects of compressor surge including steady state and transient operation.
