A case study is presented of a complete corrosion management system installation at a Western Canadian gas processing facility. This system provides on-line input of corrosion monitoring probes, process parameters, coupon data, ultrasonic measurements, and laboratory analysis data all in one integrated system. Examples are presented of some of the corrosion problems that were exposed by the system and the remedies that were taken. Major economic savings were achieved through analysis of the data, and consequential changes that were made to the operation of the plant. Many aspects of operation are still under investigation as further operational data is gathered. Based on just these early examples of corrosion control, the cost of the system has been quickly recovered.
