Q: What is the Profit® Suite Early Event Detection Toolkit? A: The Profit® Suite Early Event Detection (EED) Toolkit provides a statistical modeling and application environment to identify, localize, and support the reduction of abnormal situations in processes and plant equipment.
Q: What is an abnormal situation?A: Abnormal situations in a plant range from equipment-related faults and startup- and shutdown-related problems to major process upset – all requiring human intervention. Any of these situations can result in serious safety, operational, and economic issues for a processing plant.
Q: Does the EED toolkit integrate with Profit Suite for advanced control and optimization?A: Yes. It takes advantage of the statistical modeling capabilities of Profit Sensor Pro (Honeywell’s Soft Sensor modeling package) and the rich data import, visualization, and manipulation tools of Profit Design Studio, simplifying development and deployment of EED Models. Profit Suite applications also communicate with Asset Manager PKS to provide symptom/fault analysis.
Q: What does the fuzzy logic component do?A: The fuzzy logic component gives the user the ability to incorporate pseudo confidence bounds on desired events. This allows the user to effectively desensitize potentially problematic PCA results. It provides a tuning tool for users to attenuate the effect of noise in the process, resulting in final models balancing false positive detection against detection of actual events.
Q: How has the EED toolkit been successfully used?A: Error in temperature calculations leads to reboiler upset eventually affecting bottoms composition; Correlating compressor data with process behavior to provide far greater insight into the machine’s behavior; Valve sticking leads to loss of condenser and column capacity; Frozen DP cell leads to VL buildup, loss of reboiler, and eventual flooding.
Q: What are the system requirements to run EED?A: The EED Toolkit modeling software operates with Microsoft Windows NT and Microsoft Windows 2000. A Pentium II equivalent microprocessor or higher is recommended due to the computational requirements of this application. EED Toolkit on-line software and interface components run on Honeywell Experion Application Servers (EAS), TPS Application Nodes, as well as Microsoft Windows NT/Microsoft Windows 2000 platforms running Embedded or Oracle-based PHD.
