If you’re responsible for managing the performance of your organization’s centrifugal and axial compressors, take advantage of this freely available download and advance your knowledge and expertise.

Here are the important learning objectives:

• Learn how the compressor characteristics and operating conditions affect the potential for surge, the surge curve, and the surge controller set point.
  Learn how the compressor and piping design affect the frequency and amplitude of the flow and pressure oscillations during surge.
• Learn how the surge cycles cause compressor damage.
  Learn the relative advantages of different types of instruments in detecting surge.
• Learn how fast the approach to surge will be and how fast the flow reversal is at the start of the surge cycle.
• Learn how to generate the surge curve and the set point for the surge controller for different compressors and operating conditions.
• Learn why a backup open loop is needed in addition to the feedback loop for surge control and how to design one.
• Learn how fast the transmitter, the controller, and the control valve must be to prevent surge.
• Learn how to modify and maintain the control valve accessories to meet the stroking speed requirement.
• Learn how the surge and throughput control system designs affect the operating efficiency of the compressor.
• Learn how to assess the severity of interaction between the surge and throughput control loops and how to reduce it.
• Learn how to use a computer to monitor changes in compressor performance for maintenance and advisory control.

Greg McMillan’s book, Centrifugal and Axial Compressor Control, delves into the complex control challenges associated with these types of compressors, particularly in surge conditions. This is a unique opportunity to learn from a true industry leader.
