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.

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.

Software Highlights

• expands reporting capabilities with a performance dashboard displaying historic performance data for individual shells and the entire network as well as historic and predicted network heat duty plots
• extends HTRI methods for calculation of two-phase film heat transfer coefficients and pressure drops
• advances usability with editable tables of geometry values, display of component names on graphs, specification of separate inlet/outlet nozzle diameters, and addition of tube wall material specification
• estimates historic daily fouling costs with normalized furnace inlet temperature (NFIT) calculation
• includes the ModelView module as an option for displaying all historic and predicted data within a locked network model
• improves hydraulic calculations in data reconciliation and tracking modes
• addition of heat exchanger properties table with improved data checking
• new options for data visuals, including presentation of date-selected stream local values on the model canvas
• new option to equally distribute fouling resistances among shells in series
• calculation to rank benefits of cleaning one or more exchangers on a specified future date, from three months ahead to 24 months ahead
