Performance monitoring and predictive maintenance software for shell-and-tube heat exchanger networks

SmartPM^TM simulates complex networks of shell-and-tube heat exchangers to help engineers and plant operators manage fouling. Used in exchanger networks such as refinery preheat trains, SmartPM predicts future performance, including the effects of fouling build-up, and can help achieve energy savings and maintain throughput by scheduling exchanger cleanings.

Combining HTRI’s single- and two-phase detailed exchanger analysis methods with advanced techniques for exchanger network simulation makes SmartPM the most robust, validated thermohydraulic simulator of its type. It's use of dynamic fouling models allows engineers to evaluate the best options for mitigating fouling.

Software Highlights

• Connects SmartPM to OSIsoft^® PI System^® for two-way data transfer
• Applies different cleaning costs for online cleaning and cleaning at shutdown
• Enables setting of network throughput using known furnace firing capacity limit or network pumping capacity in cases when exchangers offline for cleaning reduce network throughput
• Ranks exchanger table to display FIT change at the end of the user-defined benefit realization period (e.g., shutdown)
• Improves estimate in poorly instrumented complex configurations by providing automatic soft sensors option
• Uses scaling parameters to predict fouling for heat exchangers where fouling mitigation devices (bundle vibration device) are attached or for heat exchangers with different metallurgy (stainless steel)
• Displays time-varying Standard Flow values for all streams
• Presents time-varying flow rate visualizations through stream scaling on model canvas
• Provides additional user option for correcting heat duty mismatches to prevent error propagation throughout networks
