This paper discusses the interaction between a centrifugal compressor and the process, and as a result, the control requirements for centrifugal compressor packages. The focus is on variable speed, upstream, and midstream applications. The impact of the interaction between system characteristics and compressor characteristics both under steady-state and transient conditions is explained. Also considered are the concepts to optimize and control the units. Special attention is given to the issue of surge avoidance. Additionally, the impact of the process and how the process dynamics interact with the compressor is analyzed, categorized, and explained.
