Centrifugal compressor surge and its prevention have drawn significant attention from manufacturers and users. An important aspect of surge avoidance lies in the design of the compressor station and, in particular, the piping upstream and downstream of the compressor. Most anti-surge systems are perfectly capable of avoiding surge during normal operating conditions. However, unplanned emergency shutdowns present a significant challenge, and surge avoidance in these cases depends to a large degree on the station layout. In this paper, data from a compressor that surged during an emergency shutdown are presented. The data are analyzed to determine the effects of surge and the rate of deceleration. Simple rules that help with proper sizing of upstream and downstream piping systems, as well as the necessary control elements are described. Furthermore, recommendations to avoid problems at start-up, as well as control problems during normal operation, are given.
