Abstract/Summary
In this presentation, learn how CHS and Inprocess have developed and implemented a digital tool to monitor the performance of heat exchangers and support maintenance planning. Using Aspen EDR in Aspen HYSYS, fouling trends were analyzed to identify units exchangers with the greatest impact on process efficiency and cost. Integrated online with real-time plant data, the monitoring tool flags when equipment performance drops below defined thresholds, enabling dynamic updates to cleaning strategies and supporting data-driven decisions that can increase throughput and reduce downtime, energy consumption, and emissions.
