Surge Control Dynamic Analysis For Centrifugal Compressor Systems

摘要

A key goal for operators with centrifugal compressors is to prevent the compressor from going into surge. This is accomplished by proper design of the piping system, associated equipment and control valves that can balance the opposing requirements associated with start-up, emergency shutdown and normal operation. The dynamic surge analysis (or surge study) evaluates, optimizes and validates the overall system design by simulating the system dynamic response to these operating scenarios and provides valuable recommendations to the design team. This article explains how an inappropriate piping system design can contribute to a surge event and outlines the steps necessary for an accurate surge analysis.
