Virtual Analyzer improves continuous manufacturing processes by providing real-time information about product quality and process variables, and/or by eliminating delays in detection of process problems due to untimely lab analysis. It provides on-line, real-time critical process information by using a combination of available on-line process measurements and advanced, neural network process modeling technologies.
Objective (Why use Virtual Analyzer) A number of production problems such as difficult to measure on-line product properties, difficult to detect malfunctioning sensors, or untimely lab analysis, pose constant challenges to process management and can add significantly to the production cost. Virtual analyzers provide real-time information on process disturbances and their effects on product properties thus making it possible to address any potential production problems as they occur. Many key process performance variables can not be measured directly on-line. They are either measured in the laboratory (e.g. product properties) or are inferred indirectly from other measurements. Recent developments in computer technologies have made possible, however, the introduction of powerful software tools ("virtual analyzers") that can predict key product properties and process performance variables in real-time.
Functional Description Virtual Analyzer diagnoses/validates on-line measurements and predicts key product/process parameters. Virtual Analyzer accesses data from DCS, SCADA, or production databases in real-time, and provides robust, secure, and compatible integration with the existing system’s application software.
System Architecture Virtual Analyzer is a software solution for prediction of key product properties and process performance variables in real-time. The system consist of four modules:
Economics Virtual Analyzer eliminates the need for expensive hardware analyzers and for frequent calibration and maintenance of product sampling systems. Where on-line instrumentation is not available or is too expensive to implement, Virtual Analyzer can provide inferred process measurements that are helpful for process diagnosis and optimization. It can also provide the needed redundancy for any unreliable and/or critical instrumentation sensors, at low implementation and maintenance cost.
